Picosecond lasers are best suited to machine materials that suffer from negative thermal effects during nanosecond laser machining with much higher performance. Nowadays, when it comes to material machining, the term "ultrafast lasers" is used more and more. It is used to distinguish picosecond and femtosecond lasers for applications. In picosecond lasers, the laser pulse length is shorter than the time required for absorbed laser energy to propagate to the substrate and is usually between 5 and 10 picoseconds (ps). Picosecond laser micromachining is becoming increasingly popular due to the outstanding superficial finish. This is accomplished due to lower heating and reduced debris-related effect. Not to mention the enhanced coupling due to the nonlinear intensity-dependent absorption and the obvious ease with which the machining effect can be achieved. The picosecond laser micromachining will produce a minimal size. This delivers features slightly smaller than one micro...

Even though it’s known as a hard-to-machine material, Tungsten carbide (WC) is widely used as a material in tools. Due to its special properties, such as dimensional stability, extreme hardness, outstanding wear resistance, and chemical inertness, tungsten carbide is utilized in many industries. Traditional mechanical machining techniques, such as electrical discharge machining (EDM) & grinding, can encounter difficulties such as tool damage, rapid tool breakage, and time-consuming repairs due to material toughness and strength. If EDM is used in processing tungsten carbide (WC), there could be many machining problems, including a heat-affected layer formed on machined surfaces and a discharge-induced rough surface. Consequently, a post-polishing process is necessary, which makes the whole manufacturing process very sluggish and raises the cost of production. Besides, for the EDM operation, a shaped electrode must be produced, which usually wears and must be remodeled or replaced...

  Femtosecond laser solutions, which include micromachining, are constantly growing and evolving across various business areas. Ultrafast lasers are predominantly used in applications where the requisite HAZ and efficiency are not achieved by traditional CW, long-pulsed fiber, nanosecond, and picosecond laser systems. A  femtosecond laser represents  10 to the −15 of a second, which is one-millionth of a billionth of a second. At given pulse energy, the laser's peak power increases as the pulse's length become shorter. Hence, femtosecond lasers have a much higher peak power than longer pulsed picoseconds, millisecond or nanosecond pulsed lasers. Since total energy is transmitted to the substance and less is drawn into heating the material, these higher peak powers result in higher removal rates in a material. These femtosecond lasers' high peak power, sometimes several-MW, disrupts the atoms and electrons in the material, resulting in what is known as a "Coulomb explos...

Ever since its invention, the value of lasers has evolved by leaps and bounds. Lasers can not only cut and micromachine quickly, but they can do so at a low cost with accuracy and speed efficiency.

  With the emergence of new tools, the technology involved in engraving techniques has really advanced. The most prevalent techniques in use today are laser engraving and micromachining. Here's an analysis of modern laser engraving and micromachining of substrates. What Is Laser Engraving & Micromachining? Laser engraving and micromachining are specialized techniques used to mark and create all kinds of images on diverse objects and surfaces. Technically speaking, both methods are known as surface or laser micromachining. They are now being used in all types of productions. Major Services Involved In Laser Micromachining In recent times, laser micromachining is used in making all kinds of services available, especially in the technological and industrial sectors. The services that could be rendered through the process include laser precision cutting, laser precision welding, laser marking and engraving, laser polishing and hardening, etc. It all depends on the distinct service ...

  High speeds and high versatility are the main benefits of laser micromachining when it comes to drilling and making holes. Micro-drilling has two distinct laser processes as with cutting: fusion drilling with pulsed lasers and additional gas support - and vaporization-induced melt ejection, such as with q-switched solid-state lasers. By choosing the proper wavelength and power density of the laser beam, almost all solid materials such as metals, semiconductors, plastics, ceramics, diamonds, etc. can be laser-drilled. Various Methods for Laser Drilling For selective roughening of surfaces for gluing and coating processes, pulse drilling of holes at a depth of some microns is used. Single-pulse methods may be used for through holes in small workpiece thicknesses. For thicker materials, percussion drilling is the first option and can be accomplished by applying several laser pulses with the appropriate depth. A combined drilling-cutting method or the multi-pass method is used for t...

Laser marking and laser engraving innovations in the pattern or mold making industry are becoming ever more prevalent. Mold makers know that machining small cavities in molds are difficult and time-consuming, and extensive hand polishing is usually required to finish the job. If the mold is either hardened or constructed of pre-hardened materials, the job is rendered much more difficult. Deep laser engraving provides an effective form of machining without contact that is effective on hardened tool steels and can penetrate hard-to-reach areas. Deep Laser Engraving Deep laser engraving is generally regarded as a machining process that removes up to 30 thousandths of an inch of material. It is often used for adding details to molds such as patterns and shapes, or for adding identification marks. Advantages of Laser Engraving A significant advantage of using picosecond and femtosecond lasers to engrave molds is that they operate well on hardened steel surfaces. It also works where...

  A wide variety of highly analytical key performance metrics and the reliability to survive harsh operating conditions requires the best technology to achieve. Femtosecond lasers can meet the variable consumer demands in an incredibly large cross-section of the industry. Today, there are potentially three major fields of use for femtosecond lasers: medical devices, micromachining small parts and advanced research projects. A significant factor behind the large-scale implementation of advanced optical technology such as femtosecond lasers is the potential to work efficiently in conventional research environments and under rough environments. Speaking more on that, we have four essential benefits of femtosecond lasermicromachining : Transparent Materials Processing In transparent materials manufacturing, femtosecond lasers are an excellent choice, providing manufacturers the chance to fine-tune the ablation and welding of glass with unparalleled thermal side effect mitigation. Micro...

  The ablation method is fundamental for laser micromachining. Conventional pulsed- laser machining processes dissociate matter at atomic and molecular levels by application of laser radiation. The absorbed laser energy is passed to the material's atomic and molecular lattice, which induces ablatement of the substance. Simultaneously, this energy is ultimately transformed into heat that disperses out of the laser spot volume beyond the laser pulse duration. However, surgically clean and extremely localized laser ablation is possible without significant damage or alteration of the underlying material, by using femtosecond laser micromachining.   Femtoseconds are the time-scale in which a process called cold ablation can develop. The principle of cold ablation is an ablation that happens in the process of femtosecond laser absorption, during the athermal state of the substance. The aim is to remove excess material before it is in a state of total thermal equilibrium, allowi...

The laser micromachining of small parts accurately and repeatability on thinner sheet metals requires a precise system. Otherwise, you're just using a sledgehammer to crack nuts and losing money in the process. The use of a high-power laser on thin metals will cause all sorts of problems that could be prevented by a less powered machine. A high-power laser, for example, is required to cut thick metal, not thin ones, so it can become unstable by under performing it. The running costs involved are not comparable with a low-powered system, either. Set-up costs can also be out of proportion to the work's value. In some cases, using a high-power laser to cut small parts can double the production costs. At Laserod, we have developed a small part laser micromachining solution for different types of metals. Our thin metal cutting and drilling system is a laser cutter optimized for micromachining small parts in both prototypes as well as industrial environments. Operating on vario...
