CA-1233 Passive Q-Switching

Educational Objectives

l   Passive Q-Switch Technique

l   Saturable Absorption

l   Q-Switched Radiation

A Cr:YAG crystal acts as a saturable absorber within the resonator. Atrain of needle like pulses are observed. The pulse frequency is influenced bythe pump power and the cavity alignment. When oscillating at higher transversalmodes two or more pulse trains appear. In combination with CA-1231 intra- andextra-cavity SHG can be shown.



CA-1234 Mirror Extension Set

Educational Objectives

l   Minimum Laser Threshold

l   Slope Efficiency

l   Laser Losses

A set of four laser mirrors with reflectivities between 80% and 99% at1064 nm are provided. The influence of the reflectivity on the laser thresholdand on the slope efficiency is shown. The maximum laser power as a function of thereflectivity is measured. The laser thresholds for different mirrors areplotted and extrapolated for a minimum threshold value.
