Laser system and method with temperature controlled crystal |
March 3, 1992 |
| A laser produces a light beam which is passed through a nonlinear crystal along a beam path. The noncritical phase matching axis of the nonlinear crystal is offset at a slight angle from the beam path. The angle of exit of the second harmonic light from the nonlinear crystal varies with |
