DPSS UV Lasers

1.STRFH UV Laser

STRFH Excellent II 355 series

ExcellentⅡ355 UV series DPSS lasers include 8.0W to 10.0W models. With relatively short pulse width (<20ns@50K), superior beam quality（M²<1.2）and perfect beam spot quality (Beam Circularity>90% ). This series lasers are widely used in precisely marking on nonmetal materials, LED etching, glass marking and FPC cutting applications.

Main characteristics:

Laser wavelength 354.7nm. Repetition rates cover a wide range (single pulse to 200 kHz).
Short pulse width （<20ns@50K）, small thermal effect on operation field.
Superior beam quality （M2<1.2）, absolutely assured in all repetition rates.
ORHAC (online refreshment for harmonic coupling) technology, long term power stability.
Unique Q-switching technology, adapts a variety of control requirements of laser applications.
Whole process intelligent digital power control technology, which can control lasers through RS232 external controller.
Industrial production process control technology, provides quality stable products.
Higher powers require chiller

Applications:

Glass Scribing and marking
Milipore punching
removal of metal and non-metal coating
flexible PCB marking and scribing
material micromachining
