…by employing a
laser having output in the ultraviolet.
As laser pulse width gets into the picosecond
domain, an entirely different mechanism for
material removal comes into play, called photo
ablation. This process occurs because short
laser pulse widths lead to…
…pulse laser products include femtosecond lasers with up to 900 fs pulse widths and picosecond lasers with up to 80 MHz repetition rates. Pulsed Q-Switched Pulsed Q-Switched A complete portfolio of Q-switched DPSS lasers is available at wavelengths in the infrared, visible, and ultraviolet, with a…
…diode-pumped UV lasers are ideal for drilling <70 µm diameter vias in RCC and PTFE-based dielectrics and copper. Related Products AVIA NX HyperRapid NX Micromachining with Industrial Lasers Excimer and fiber lasers enable industrial micromachining. Ultraviolet (UV) laser light is an ideal…

Materials processing experts face a wide range of choices in determining
the right laser for their production needs.
Nanosecond or picosecond; ultraviolet, green or infrared; CO2, DPSS or fiber
lasers. Choosing between these lasers…
With pulse widths from <25 fs to the picosecond
regime, pulse energies up to >13 mJ and output power
up to >16W, there is always a Legend Elite model for
your ultrafast amplifier application.
different approaches that largely eliminate the HAZ. One method is to use
a laser with output in the ultraviolet. An even better approach uses laser
pulses in the picosecond domain or shorter. Here the high peak fluence
drives multiphoton absorption stripping electrons…

The excimer's short (ultraviolet) laser wavelengths enable
clean microprocessing of glass. The large pulse energy and

…pulse width lasers, and
ultrafast (picosecond and femtosecond) lasers yield particles hundreds of nanometers in size.
Nanosecond pulse width lasers, operating in either the green (532 nm) or ultraviolet (355 nm),
are usually employed in "bottom-up" cutting. Here, the laser enters…
…Wavelengths from the ultraviolet to infrared
regions are readily accessible.
A full range of power meters, autocorrelators,
spectrometers, IR/UV viewers, and more are
available from Coherent for use with Mira
ultrafast laser systems.
…in which case there are two main routes to minimizing the HAZ: one is to use an ultraviolet laser; the other generally more effective method is to use ultrashort laser pulses of durations in the picosecond domain or shorter. Here, a combination of high peak power and tight focusing creates…
