Title:
ALL SOLID-STATE LASER LIGHT SOURCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/109235
Kind Code:
A1
Abstract:
An all solid-state laser light source device comprises a diode-pumped laser (10) and the following devices sequentially arranged in an optical path direction of laser light: a coupling optical fiber (20), a coupling lens assembly (30), and a resonant cavity (40). An anisotropic laser crystal (50) is provided in the resonant cavity (40). Absorption spectra of the anisotropic laser crystal (50) comprise a π polarization absorption spectrum and a σ polarization absorption spectrum. Each of the π polarization absorption spectrum and the σ polarization absorption spectrum has a peak pump region (F) and a left pump region (L) and a right pump region (R) arranged on either side of the peak pump region (F). Pump light outputted by diode-pumped laser (10) has a wavelength λ falling within the left pump region (L) or the right pump region (R).
