  • Patent number: 11005229
    Abstract: An all solid-state laser light source device comprises a diode-pump laser and the following devices sequentially arranged in an optical path direction of laser light: a coupling optical fiber, a coupling lens assembly, and a resonant cavity. An anisotropic laser crystal is provided in the resonant cavity. Absorption spectra of the anisotropic laser crystal comprise a ? polarization absorption spectrum and a ? polarization absorption spectrum. Each of the ? polarization absorption spectrum and the ? polarization absorption spectrum has a peak pump region and a left pump region and a right pump region arranged on either side of the peak pump region. Pump light outputted by diode-pump laser has a wavelength ? falling within the left pump region or the right pump region.
