Cr4+:YAG (Y3Al5O12) crystal is ideal for passive Q-switch operation of Nd:YAG and other Nd3+ or Yb3+ doped laser crystals in the wavelength range of 900 nm to 1200 nm. 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. A remarkable feature of Cr4+:YAG is the high damage threshold of >10 J/cm2@1064 nm, 10 ns. Its absorption band extends from 900 nm to 1200 nm and peaks around 1060 nm with a very large absorption cross-section.

Descriptions:

Cr4+:YAG (Y3Al5O12) Chromium Doped Yttrium AIuminum Garnet crystal is ideal for passive Q-switch operation of Nd:YAG and other Nd3+ or Yb3+ doped laser crystals in the wavelength range of 900 nm to 1200 nm.

Main applications:

1) Passively Q-switched lasers for laser rangefinders, LIDAR, and LIBS systems

2) Laser systems where short pulses are required

Advantages:

1) High chemica stability and reliability

2) Easy to operate

3) Long lifetime and good thermal conductivity

Why Choose HGO ?

HG OPTRONICS.,INC. supplies very high quality of Cr4+:YAG passive Q-switch crystals Chromium Doped Yttrium AIuminum Garnet. The use of high quality starting materials for crystal growth, boule interferometry, and precise measurement of initial transmission and absorption using transmission spectroscopy and ZYGO measurements, assures that each crystal will comply with customer’s specification and perform well in laser system.

Tolerance of initial transmission can be well controlled in as high precision as 0.5% which could be very essential to some delicate laser systems.

Besides, based on HGO’s advanced bonding technology, high quality of diffusion bonding between Nd3+, Yb3+ or other ions doped YAG host laser crystals and CrYAG are available from stock or for customization.

What is more,HGO have mature solutions for different laser parameters especially in microchips solution and our engineer are very glad to discuss and provide solutions for customers.
