Abstract
The free spectral range dependent on the length of an oscillator is put in a relation of integral times with respect to the free spectral range dependent on the length of at least a nonlinear optical crystal or a wavelength selection SHG output element. Thereby, reduced noise in the output of a second-harmonic generator is intended.
