CA-1231 / 1232 Options for Nd:YAG Laser
CA-1231 Frequency Doubling
- Behavior of Nonlinear Optics
- Second Harmonic Generation
- Power of SHG-Radiation
A KTP crystal converts the Nd:YAG emission intra-cavity to green light. For green emission above 5 mW an output coupler mirror highly transmissive at 532 nm is provided. Using an IR-absorbing filter the quadratic response of the SHG process is measured. Transverse cavity modes of the Nd:YAG laser are visualized by SHG impressively.

CA-1232 Active Q-Switching
- Active Q-Switch Technique
- Electro-Optical Modulator
- Q-Switching Behavior
A LiNbO3-Pockels cell changes the polarization state of the Nd:YAG emission. A Brewster plate introduces losses and laser operation is suppressed. When switching the cell, the losses are minimized and a laser pulse builds up. Switching voltage and frequency are adjusted by the Pockels cell controller. In combination with CA-1231 intra- and extra-cavity SHG can be shown.
