Linearly Polarizing Laser Mirror for Q-switched Operation

A polarizing laser mirror made with glancing angle deposition of TiO2 could withstand a train of 2.7 ns pulses with peak power density of around 800 MW/cm2 and a polarization extinction ratio of 1000 when used as an output coupler of a passively Q-switched (Yb0.1Y0.9)3Al5O12 ceramic laser.
