Nd,Ce:YAG is a co-doped gain material for compact and air-cooled laser configurations. Reference rods address continuous-wave, pulsed, Q-switched and frequency-converted operation, with dopant level and finish specified for the intended system.
Properties, applications and specifications
Nd,Ce:YAG is used in miniature and air-cooled laser systems. The reference describes high efficiency, low threshold, resistance to ultraviolet exposure and high repetition rates. Operating modes include CW, pulsed, Q-switched, mode-locked and frequency-doubled operation, as well as high average powers.
Advantages:
1. Low threshold 2. Very high slope efficiency 3. Good thermal stability 4. High optical quality 5. Good anti-UV irradiation property
