Cr4+:YAG
- Passive Q-switches or saturable absorbers
- More robust than dyes or color centers
- Ideal the material of choice for 1 um Nd lasers.
- Cheap but high quality
PRODUCT DESCRIPTION
Cr4+:Y3Al5O12- Passive Q-switches or saturable absorbers provide high power laser pulses without electro-optic Q-switches, thereby reducing the package size and eliminating a high voltage power supply. Cr4+:YAG is more robust than dyes or color centers and is the material of choice for 1 um Nd lasers.
