Problems solved by technology
[0004] The object of the present invention is to provide a high-energy laser of one hundred hertz and one hundred nanoseconds, which solves the problem of complex system, low efficiency, poor beam quality, large volume and problems existing in the existing high-energy pulse lasers for obtaining hundreds of hertz and one hundred nanoseconds pulse width. Disadvantages such as high cost are based on the ring resonator, and the 808nm quasi-continuous semiconductor laser module is used as the pumping source to pump the Nd:YAG crystal, and the optical length of the resonator is increased through the multi-pass reflection optical path of the slab mirror, which is convenient and quick to realize. An all-solid-state laser with a pulse width of 100 Hz and 100 nanoseconds,

The invention relates to a hundred-Hertz hundred-nanosecond large energy laser. The hundred-Hertz hundred-nanosecond large energy laser is characterized in that a plane output mirror, a Q switch, a polarization splitting prism, a quasi-continuous semiconductor laser module pumping source, a laser crystal, a Faraday rotator, a 1 / 2 lambda wave-plate and a fourth plane total reflective mirror are successively arranged on a laser crystal optical path; the plane of reflection of the plane output mirror is opposite to the laser crystal, and displays an included angle opposite to the laser crystal optical path; and the hundred-Hertz hundred-nanosecond large energy laser solves the problem that a current large energy pulse laser for acquiring hundred-Hertz hundred-nanosecond pulse width has the disadvantages of complicated system, low efficiency, low beam quality, large volume and high cost, is based on an annular resonant cavity, takes a 808nm quasi-continuous semiconductor laser module as the pumping source to pump an Nd: YAG crystal, increases the optical length of the resonant cavity by means of multipass reflected optical path of lath reflectors, and can conveniently and quickly implement a total solid state laser of hundred-Hertz hundred-nanosecond pulse width.
Description
technical field [0001] The invention relates to a hundreds-hertz-hundred-nanosecond high-energy laser, which belongs to the technical field of all-solid-state lasers, and mainly relates to a side-pumped quasi-continuous semiconductor laser module, which realizes a pulse width of hundreds of nanoseconds at a working frequency of one hundred hertz. High energy laser. Background technique [0002] Some special scientific experiments require hundreds of nanosecond high-energy pulsed lasers with a wide pulse width. This pulse-width laser can be used as fundamental frequency light for extracavity and intracavity frequency doubling to output a 532nm pulse laser with a pulse width of 100 nanoseconds, and the 532nm laser can be used as a pump source for a dye laser. [0003] At present, the hundred-nanosecond high-energy pulsed laser mainly realizes the output of the high-frequency hundred-nanosecond hundred-hertz laser through: 1) the modulation of the Q switch in the standing wave...
