CA-1231 Frequency Doubling

Educational Objectives

l   Behavior of Nonlinear Optics

l   Second Harmonic Generation

l   Power of SHG-Radiation

A KTP crystalconverts the Nd:YAG emission intra-cavity to green light. For green emissionabove 5 mW an outputcoupler mirror highly transmissive at532 nm is provided.Using an IR-absorbing filter the quadratic response of the SHG process ismeasured. Transverse cavity modes of the Nd:YAG laser are visualized by SHG impressively.



CA-1232 Active Q-Switching

Educational Objectives

l   Active Q-Switch Technique

l   Electro-Optical Modulator

l   Q-Switching Behavior

A LiNbO3-Pockels cell changes the polarization state of the Nd:YAGemission. 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. Incombination with CA-1231 intra- and extra-cavity SHG can be shown.
