Optical crystals can exhibit distinct styles of optical nonlinearities, that may be utilized in numerous strategies: BBO is the only NLO material which can be applied to make the fifth harmonic generation (5HG) of Nd:YAG lasers at 213 nm. Thanks to a little acceptance angle and large angular walk

Crystals which might be non-critically stage-matched within a crystal oven may well exhibit problems in the event the crystal temperature is changed way too speedily or as well often. In particular, anti-reflection coatings might be ruined as a consequence of distinct thermal enlargement coefficient
