Cr:YAG > Cr4+:YAG

Introduction

Cr4+: YAG Crystal is an excellent crystal for passively Q-switching diode pumped or lamp-pumped Nd:YAG Nd:YLF YVO4 or other Nd and Yb doped lasers at wavelength from 0.8 to 1.2 μm. 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. [Advantage] High chemical stability and reliability Being easy to be operated High damage threshold(＞500MW/cm2) As high power solid state and compact passive Q-Switch Long life time and good thermal conductivity

The preliminary experiments of our Cr4+:YAG showed that the pulse width of passively Q-switched lasers could be as short as 5ns for diode pumped Nd: YAG lasers and repetition as high as 10kHz for diode pumped Nd: YVO4 lasers. Furthermore, an efficient green output @ 532nm, and UV output @ 355nm and 266nm were generated, after a subsequent intracavity SHG in KTP or LBO, THG and 4HG in LBO and BBO for diode pumped and passive Q-switched Nd: YAG and Nd: YVO4 lasers.

Cr: YAG is also a laser crystal with tunable output from 1.35μm to 1.55μm.  It can generate ultrashort pulse laser (to fs pulsed) when pumped by Nd: YAG laser at 1.064μm.

Note:

When ordering Cr4+: YAG crystal, please specify the size, initial transmission and coatings. For further information, please contact Banner Union.
