Based on the basic principles of laser damage, researchers have found a breaking through point to solve the problem of laser damage to optical components. But it is very difficult to effectively suppress the source of laser damage in the manufacturing process. Given the variety and complexity of

In 1962, the American scientist McClung F J reported for the first time that the silver mirror of the ruby laser resonator had hole burning damage, which was the first public report on the laser damage of optical components. The subsequent invention of Q-switching technology and mode-locking

MEASUREMENT TECHNIQUEThe measurement technique consists primarily of a measurement of the variation of the angle of deviation with temperature. The crystals to be measured were 60-60-60° prisms approximately 15 mm on a side. They were attached to a temperature-controlled mount in a vacuum chamber.

The variant of refractive indices with temperature is an essential crystal parameter in nonlinear optics. it is well known that the wavelength at which 90° phase-matched 2nd-harmonic era happens depends on temperature. the variation of this wavelength with temperature can be predicted with a
