the non-linear crystal, there is a particular angle (the phase matched angle), at which the
crystal’s birefringence gives the combined photon, with both different frequency and
polarization, the same velocity as the input photons.
The doubling crystal is enclosed in an oven kept at a constant temperature of 35° C, to
prevent water vapor from damaging the crystal and to optimize and stabilize the doubled
output. A toggle switch on the PIV cover controls a motor-driven oven rotation stage for
easy optimization of the phase matching angle.

PIV Operation
Startup
1. Lower the PIV beam dump to engage it.
2. Turn on both lasers and allow them to come to warm up; follow the instructions in
your Surelite or Powerlite YAG laser manual. If desired, take burns and/or check
beam energies to verify proper operation.
