Abstract

The invention discloses a low repetition frequency passively Q-switched regenerative amplification lamp-pumped pico-second laser which comprises a seed source. The seed source comprising a saturable absorber mirror used for passive Q-switching is provided with a resonant cavity and generates picosecond pulse seed light as laser light; one side of the output end of the seed source is provided with a regenerative amplification system which repeatedly oscillates the laser light entering into the seed source, an optical isolation system which prevents picosecond pulse seed light from returning to the seed source is disposed between the regenerative amplification system and the output end of the seed source; the optical isolation system is provided with a structure, the structure is capable of transferring the laser light which is oscillated repeatedly and transferred back by the regenerative amplification system to the outside world. According to the low repetition frequency passively Q-switched regenerative amplification lamp-pumped pico-second laser, a pico-second laser with a high-energy single pulse, a short pulse width and low repetition frequency can be obtained, the pico-second laser has the advantages that the cost is low and the structure is compact, moreover, no high voltage power supply is required, the mechanical stability is high.

Description

technical field [0001] The invention relates to the technical field of picosecond lasers, in particular to a low repetition frequency passive Q-switched regenerative amplifier lamp-pumped picosecond laser. Background technique [0002] Since the birth of picosecond lasers, mode-locking technology has been the mainstream technology for generating picosecond laser pulses. However, the mode-locked laser system has the disadvantages of difficult optical path calibration, the mode-locking process is easily disturbed by the outside world, and the mechanical stability is not high enough. Compared with the above-mentioned shortcomings of mode-locked lasers, passive Q-switched lasers have the advantages of simple structure and good stability. At the same time, passive Q-switching technology does not require high-voltage power supply, electronic control equipment, electro-optic switches and other devices, so it has high safety, simplicity and practicability, and is widely used in sma...
