…diode-pumped solid-state (DPSS) lasers, lend themselves to be operated both in CW or pulsed operation.
Other lasers, like laser diodes or OPSLs, are not suitable at all for pulsed operations. Within this context, we define as "pulsed" laser devices that produce
pulses of 0.5 to 500 ns.…
Actively Q-Switched Compact DPSS sub-ns Laser The lasers of the HELIOS series are compact, rugged systems with high pulse energy and pulse duration of only a few hundred picoseconds. This allows for a precision and quality in micromachining and microelectronics applications which are not possible…

few years ago, we saw fast growth in the
use of excimers and visible nanosecond
DPSS [diode-pumped solid-state] lasers;
subsequently, there was a move toward
ultraviolet DPSS lasers."
The next big development came in the
form of industrial ultrafast lasers, which…
