355nm Ultra Violet UV DPSS Laser
355nm Ultra Violet UV DPSS laser is a new laser technology, widely used in laser cutting and engraving. 355nm laser is used in university experiments, however the highest continuous power is < 20mW. If you need higher power, the pulses 355nm UV laser can reach 1000mW (1W). Most of the users install 355nm DPSS laser into engraving machines.
There are four types :
- CW ultraviolet laser at 355 nm；
- Passively Q-switched ultraviolet laser at 355 nm,
- Actively Q-switched ultraviolet laser at 355 nm,
- Fiber coupled laser system at 355 nm
