Abstract
A laser system includes a pump laser device outputting pump laser light having a first wavelength, a signal laser device outputting signal laser light having a second wavelength, and an amplification system including optical parametric crystals outputting amplification light. The optical parametric crystals include first and second optical parametric crystals. The amplification system is arranged such that beam waist positions of first amplification light and the pump laser light coincide with each other, and that the first amplification light and the pump laser light are coaxially incident on the second optical parametric crystal; and includes a first beam diameter adjustment optical system in which a ratio of a beam waist diameter of the pump laser light to that of the first amplification light is set larger than a ratio of a beam waist diameter of the pump laser light to that of the signal laser light.
