Credo SHG

Second Harmonic Generation

For the extension of the Credo‘s tuning range into the blue spectral region, second harmonic generation (SHG) is used.
The unit provides rotation stages for non-linear crystals and compensators. The entire unit is enclosed to protect it from dust and excessive humidity.
It is possible to match two non-linear crystal for higher conversion efficiency. This option is recommended for pump power exceeding 80 Watt at 532 nm and 50 Watt at 355 nm.
