Abstract

The invention relates to an optical parametric amplifying system based on an all-fiber laser. The technical proposal of the invention is that: the optical parametric amplifying system comprises a pumping source, a signal source, a sync generator, an amplifier and a compressor; the signal source triggers the sync generator which controls the pumping source; the signal source and the pumping source are simultaneously accessed to the amplifier which is accessed to the compressor. The invention provides an optical parametric amplifying system based on an all-fiber laser which has the advantages of compact structure, stable performance, good light beam quality, high signal-to-noise ratio and high single-pass gain so as to solve the technical problems of difficulty in maintaining the whole system, low stability, loose structure and easy generation of optical damage in a chirped pulse optical parametric amplifier in the background technology.

Description

technical field [0001] The invention relates to an optical parameter amplification system based on an all-fiber laser. Background technique [0002] The development of femtosecond lasers with super energy and extremely short pulse width directly drives the research of physics, chemistry, biology, materials and information science into the field of microscopic ultrafast processes. In particular, the use of chirped pulse optical parametric amplification technology to generate ultra-intensive and ultra-short femtosecond lasers has extremely important application value in the fields of strong field physics, X-rays, attosecond science, and image information processing technology. It is particularly important to research and develop chirped pulse optical parametric amplifiers with compact structure, small size and high stability. [0003] Traditional chirped pulse optical parametric amplifiers are generally composed of femtosecond oscillators, stretchers, amplifiers, and compress...
