摘要
This disclosure provides an optical parametric oscillator, comprising, in a light path, a first lens, a laser crystal, a second lens, a nonlinear optical crystal, and a third lens in this order, wherein an optical parametric oscillation chamber is formed between the second lens and the third lens, and the nonlinear optical crystal is a monoclinic Ga2S3 crystal, the space group of the monoclinic Ga2S3 crystal is Cc, and the unit cell parameters are a=11.1 Å, b=6.4 Å, c=7.0 Å, α=90°, β=121°, γ=90°, and Z=4.
