Problems solved by technology

[0003] Most of the currently used passive mode-locked Nd:YAG lasers are pumped by xenon lamps. The time drift between the laser pulses output by such pumped lasers and the electrical trigger signal of external synchronization is between 5 and 55 microseconds, which is far from Far from meeting the needs of some research applications, it is a technical problem that needs to be solved urgently

Abstract

An outgoing high stabilized passive modelocking Nd:YAG ps laser is to set a totally reflecting mirror at a side, an output mirror at the other side of a horizontal optical axis of a mounting board, a tankage at a side of the totally reflecting mirror, a laser cavity at a side of the output mirror between the two mirros, to set a mode selector with clear aperture between the tankage and the laser cavity and a light drift controller between the laser cavity and output micror which is inserted into a laser oscillation level made up of totally reflecting mirror, tankage, mode selector, laser cavity and output mirror to control to output pulse laser drift time below 100 micro s, stabilizing the output energy within 10%.

Description

technical field [0001] The invention belongs to the field of laser technology, and in particular relates to a passive mode-locked Nd:YAG picosecond laser with high stability of light emission time. Background technique [0002] Mode-locked lasers are used to generate ultrashort pulse lasers. In some application areas, mode-locked lasers are required to generate single laser pulses with picosecond width, such as holography of ultrafast phenomena. If the duration of the phenomenon being diagnosed is very short, if the laser pulse and the phenomenon cannot be synchronized as the illumination source for holography, it is impossible to capture the holographic image and other information of the ultrafast phenomenon. If there is a strict time relationship between the external synchronization signal and the ultrafast phenomenon, in order to capture the holographic image of the ultrafast phenomenon, it is required that the drift between the external synchronization signal and the li...
