Embodiment Construction

[0030] The integrated ultrashort pulse laser system with fiber seeds of the present invention adopts an all-fiber ultrashort pulse oscillator as a seed light source, and the all-fiber ultrashort pulse oscillator adopts a highly reliable fiber-coupled semiconductor pump laser, and the all-fiber ultrashort pulse oscillates The optical path of the device is entirely composed of optical fibers and optical fiber components, and the optical fiber and optical fiber components are connected by optical fiber fusion technology, and the entire optical path is completely enclosed in the optical fiber waveguide. The fully enclosed optical path is isolated from the external environment, which makes the operation of the all-fiber ultrashort pulse oscillator more reliable, can output high-stability seed light, and can work in relatively harsh environments. The optical fiber form is easier to dissipate heat than other forms, and does not require water cooling. In the case of ensuring the neces...

Description

technical field [0001] The invention relates to the technology of ultrashort laser systems such as picoseconds and femtoseconds, in particular to an integrated ultrashort pulse laser system with fiber seeds and a frequency doubling system thereof. Background technique [0002] Since the 1980s, with the development of mode-locking technology, picosecond and femtosecond lasers have experienced the development from dyes to Kerr mode-locked, semiconductor saturable absorber mirrors (SESAM). Self-mode-locked titanium-sapphire oscillators are the most widely used picosecond and femtosecond solid-state oscillators so far. The development of high-power semiconductor-pumped 532nm solid-state laser technology, high-power optical-pumped semiconductor laser technology, and semiconductor laser direct pumping technology has led to the emergence of picosecond and femtosecond oscillators in the form of real commercial products, and the pulse width can reach 10fs In the following, the resea...
