Passive q-switch Cr4+ Yag Laser Rod Cr:Y3Al5O12
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
1.High chemica stability and raliability
2.High damage threshold of 500-1000 MW/cm2
3.Long life time and good thermal conductivity
4.Being easy to be operated
Applications
1.Passively Q-switched lasers for laser rangefinders, LIDAR and LIBS systems
2.Laser systems where short pulses are required.
