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...
