…tens of picoseconds. To enable this process, nanosecond pulses with energies of tens or hundreds of millijoules are necessary and UV wavelengths are usually preferred. These requirements match well the performances of excimer lasers. The first laser deposition experiments took place in the mid to…

…reduced compared to nanosecond lasers. With picosecond lasers, a
much higher portion of the total laser power is used to remove material, rather than produce
unwanted heating. Second, because the pulsewidth is a thousand times shorter than a
nanosecond laser, the peak power to average…

Laser User Issue 74, Summer 2014 11 Many established marking applications are quite cost sensitive in terms of both capital cost and the cost per mark. As a result, such applications typically make use of Q-switched, diode-pumped, solid-state (DPSS) lasers with nanosecond pulse widths, CO2 lasers,

Traditional Laser Power Sensors The two technologies that have been in use for decades for measuring the average power of lasers are thermopile and semiconductor photodiode. Thermopiles have been the main choice for high power lasers. In thermopiles,…
