Abstract
A potassium fluoroboratoberyllate crystal oblique-incidence laser frequency multiplier, comprising: a flake-like potassium fluoroboratoberyllate crystal having parallel front and back polished surfaces; a front antireflection film and a back antireflection film; a columnar crystal support provided with a square holding slot and a light through-hole; and external heating jackets; the crystal is disposed in the square holding slot, the front and back surfaces of the crystal conforming to a main surface of the square holding slot, a normal of the main surface of the holding slot forming an angle θ with the central axis of the crystal support; a laser at a fundamental frequency passes through the front antireflection film, and a frequency-multiplied laser generated in the crystal is transmitted out through the back antireflection film. The present invention has a simple structure and a low cost, and is suitable for medium- and high-power laser systems.
