Picosecond laser micromachining offers revolutionary accuracy rivaled only by femtosecond machining. Laserod specializes in providing devices for each form of cutting.
What is micromachining?
Micromachining is an incredibly precise procedure for generating demanding electronics. Cuts, angles, and surfaces for microchips, circuit boards, semiconductors, and medical equipment must be accurate as tolerance ratings are typically low.
Short burst lasers with short wavelengths provide the control and power required to power the modern world. These devices are made for demanding applications in such fields as electronics and medical equipment production.
Types of laser machining
Manufacturers define laser machining by the pulse rate of the laser with wavelengths that often match. Femtosecond lasers have pulse rates of less than one femtosecond while picosecond lasers have wavelengths of less than one picosecond.
The higher the pulse rate, the more powerful the laser typically is. However, since the wavelength defines power, some femtosecond lasers are used in medical procedures such as cataract removal.
When are picosecond lasers used instead of femtosecond lasers?
Many companies provide picosecond lasers for medical applications. They are typically less powerful than femtosecond lasers which yield to their use in devices targeted at tattoo removal as well as dermatological procedures.
Femtosecond lasers predominate in the world of electronics and device manufacturing where strong metals and materials need to be cut to exact specifications such as in the creation of a high-end automobile, computers, telescopes, and pacemakers.
Precision laser cutting for medical procedures
The FDA approved picosecond lasers for the removal of tattoos and skin pigments. Since this approval, the organization also approved equipment for skin rejuvenation.
The devices tend to be highly stable, yielding to use in a variety of medical procedures. Beam quality and stability are superb, giving a trained user incredible control over the procedure.
Picosecond lasers in manufacturing
The same stability, pulse widths, and features that make picosecond lasers safe for medical devices work for certain manufacturing processes. These lasers work well in high-precision environments where a femtosecond laser is not necessary.
Laserod systems stand up to demanding around the clock use with the capability to cut wafers from material somewhat softer than that cut with a femtosecond laser. Cut widths are somewhat larger as well.
Solid state lasers for machining
Laserod does not only provide picosecond control but top-of-the-line solid-state lasers as well. Solid-state devices offer even more control.
Consider that traditional CO2 lasers have wavelengths of over 10 microns. Solid state lasers achieve 1.06 microns with spot sizes of only 12 microns compared with 120 microns for their CO2 counterparts.
Picosecond laser micromachining
Picosecond laser machining is the perfect solution for manufacturing certain types of medical devices where a femtosecond laser is not needed. The still short wavelength and small pulse rate make them the perfect solution for many industries.
Laserod, with over 40 years of experience uses solid-state lasers to cut wafers and aid in the production of electronics. When you need precision, we can help.
