Product Details

Cr4:YAG Passive Q-Switch Crystals

Cr4+:YAG crystals have several advantages when compared to traditional Passive Q-switching choices such as organic dyes and colour centres materials. Crystal Passive Q-switch is preferred for simplicity of manufacturing and operation, low cost, and reduced system size and weight. Cr4+:YAG is chemically stable, UV resistant and it is durable. Cr4+:YAG will operate over a wide range of temperatures and conditions. The good thermal conductivity of Cr4+:YAG is well suited for high average power applications.

 

Main features

* High damage threshold of 500-1000 MW/cm2
* High chemical stability and reliability
* Long life time and good thermal conductivity
* Compact passive Q-Switch
* Being easy to be operated

 
Application examples

* Passively Q-switched lasers for laser rangefinders, LIDAR and LIBS systems
* Laser systems where short pulses are required.
