Abstract

The invention relates to a solid laser with adjustable pulse width from a hundred picoseconds to a nanosecond and solves problems of complicated structure and high cost of a narrow-pulse-width large-energy laser structure obtained by means of a mode-locking technique in combination with amplification technology. Linear polarized light generated by a seed light laser successively passes an isolator, a shaper 1, a polarization device 1, an amplifier 1, and a polarization device 2 and then enters a SBS pulse compressor. Light returned from the SBS pulse compressor successively passes the polarization device 2, the amplifier 1, the polarization device 1, the shaper 2 and the amplifier 2 and then exits from amplifier 2. The solid laser is simple in structure, lower in cost compared with a product in the prior art, large in output energy, good in the quality of output light beams, and suitable for the fields of laser medicine, nonlinear optics, precision machining and laser communication.

Description

technical field [0001] The invention relates to a solid-state laser, in particular to a solid-state laser with adjustable pulse width from picoseconds to nanoseconds, and belongs to the field of lasers. Background technique [0002] Solid-state lasers with narrow pulse width and high energy have broad application prospects in the fields of laser medicine, nonlinear optics, precision processing and laser communication. At present, in order to obtain the output of sub-nanosecond or picosecond pulses with greater energy, it is often necessary to use semiconductor saturable absorbing mirror (SESAM) mode-locking technology to obtain nano-joule-level mode-locked sequences, and then combine regenerative amplifiers to obtain millijoule output. , and finally the pulse is further amplified by a traveling wave amplifier. The structure of this method is relatively complicated, and the regenerative amplifier has higher requirements for signal control, and the price is relatively expensi...
