Applications:
Optical activation for an optically triggered power transistor
In a passively Q-switched laser, instead of an electrically controlled modulator, a saturable absorber is used. In its unsaturated state, it introduces a high optical loss. The laser gain must overcome that loss before lasing can start. When the laser radiation becomes stronger, it eventually saturates the losses – i.e., it reduces them to a much lower value. From this point on, the laser power rises rapidly until the gain is also saturated.
Active and Passive Q Switching
CW 355 nm Lasers
CW 355 nm DPSS Lasers are ideal for applications requiring up to 20 mW of 355 nm UV laser light with a long operating lifetime . These lasers are commonly used for fluorescence excitation and a broad spectrum of other applications.
Passively Q-switched 355 nm Lasers
Passively Q-switched 355 nm DPSS Lasers are ideal for applications requiring a short wavelength or high photon energy. These lasers are commonly used for fluorescence excitation, Raman spectroscopy, material processing, and a broad range of other applications.
AOM Q-switched 355 nm Lasers
AOM Q-switched 355 nm DPSS Lasers are ideal for applications requiring the highest available peak power and/or single pulse energy at 355 nm. The embedded AOM gives the user direct control over the output pulses, enabling a specified frequency or even a single pulse to be emitted. These lasers are commonly used for materials processing, marking, Raman Spectroscopy, biological experimentation and a broad spectrum of other applications.
