Problems solved by technology

Although the multi-pulse beam generator uses optical fiber to extend the optical path difference between optical pulses to obtain multi-pulse output, the optical fiber is too long and the optical path difference is too large to obtain high repetition frequency optical pulse output. The incident light is polarized light

Abstract

The invention discloses a light pulse frequency raiser. The light pulse frequency raiser comprises a light collimating device, an optical isolator, a primary beam splitter mirror, multiple total reflective mirrors and multiple secondary beam splitter mirrors. The reflection direction of the incident light of each secondary beam splitter mirror is provided with a total reflective mirror; the multiple secondary beam splitter mirrors form a first beam splitter mirror group and a second secondary beam splitter mirror group, and the multiple secondary beam splitter mirrors in each beam splitter mirror group are arranged to be connected in series; and the incident light is divided into two beams of light through an incident light inlet, one beam of light successively enters each secondary beam splitter mirror in the first secondary beam splitter mirror group through the primary beam splitter mirror, and the other beam of light enters each secondary beam splitter mirror in the second secondary beam splitter mirror group after being reflected by the primary beam splitter mirror, and light reflected by all the secondary beam splitter mirrors, after being totally reflected by the primary beam splitter mirror, is successively outputted via an emitting light pulse outlet. According to the invention, the light pulse frequency is increased, so that the repetition frequency of seed light can be further improved, a new method is provided for the amplification of a multi-pulse laser and the realization of a high-frequency laser, and the development of the laser industry and high-frequency light pulses is facilitated.

Description

technical field [0001] The invention belongs to the field of laser technology, and more specifically relates to an optical pulse multiplier. Background technique [0002] With the development of the laser industry, further requirements are put forward for the power of the laser and the effect of the optical pulse. Especially in laser drilling, laser processing, materials, biology and other research fields, high repetition frequency pulse lasers are more and more favored by the industry, and are also ideal for ultra-fine laser processing, high-precision satellite laser ranging and other fields. The light source plays an increasingly important role in the technological transformation and upgrading of my country's advanced manufacturing industry and the establishment of the national satellite ranging network. [0003] In the laser, due to the limitation of the length of the resonator, especially in the ultrashort pulse generated by mode locking, it is not easy to obtain a high ...
