Co:Spinel – Passive Q-Switch crystals

Compact eye-safe q-switched lasers play an important role in defense and civil applications such as LIDAR, LIBS (laser-induced breakdown spectroscopy), range-finding and micromachining.

The main challenge typically involved in making compact resonators with saturable absorbers is laser-induced damage within optical components. Short resonator lengths and high peak powers           require optimal efficiency for each component. By understanding the challenges and manufacturing limits, we help our customers to reduce the length of laser resonators and handle higher fluencies.

We design coatings in-house for high LIDT, low reflectivity, partial reflectivity or low-loss high-reflectivity resonator coatings on Co:Spinel monocrystal and ceramics. Our know-how allows us to reach     ultimate results of > 50J/cm² @ 1535nm for mass-production components based on Co:MgAl₂O₄ crystals.
