Abstract

The invention discloses a tunable ultrashort pulse fiber optic parametric oscillator and relates to the fields of parametric oscillators and lasers. The oscillator comprises a tunable laser, an isolator, an intensity modulator, a first amplifier, a filter, a phase modulator, a second amplifier, a first polarization controller, a circulator, a chirped fiber grating, a wavelength division multiplexer, a high-nonlinearity optical fiber, an optical fiber coupler and a second polarization controller. The oscillator adopts a time lens system to compress optical pulse to realize an ultrashort pulse source with tunable repetition frequency and operating wavelength, the repetition frequency is decided by a radio frequency signal applied to a time lens and is very easy to be synchronous to the parametric oscillator. Through utilization of the tunable characteristics of the repetition frequency and the wavelength of the light source of the time lens and combination of time dispersion tuning and pump wavelength tuning mechanism, the fiber optic parametric oscillator can realize the ultrashort pulse laser output at tunable wide working waveband and high pulse quality.

Description

technical field [0001] The invention relates to the fields of parametric oscillators and lasers, and in particular to a tunable ultrashort pulse fiber parametric oscillator. Background technique [0002] Ultrashort pulse light source (picosecond, femtosecond level) has become an indispensable tool for modern science and production, and is widely used in various scientific research and industrial fields, such as nonlinear optics, ultrafast spectroscopy, bio-optics, photochemistry, micro Nanoprocessing, etc. How to develop a high-performance tunable ultrashort pulse laser source has become an urgent task to open up many exciting applications. [0003] In a typical nonlinear parametric process, such as four-wave mixing (Four-wave mixing), a beam of high-power pump light and a beam of signal light interact in a nonlinear medium to generate a beam of idler light. Pu light energy is transferred to signal light and idler light at the same time to achieve gain amplification. Plac...
