Description

technical field [0001] The invention relates to an optical parameter amplification laser system, belonging to ultrashort pulse generation technology. In particular, a carrier envelope phase (hereinafter referred to as CEP) stable dual-wavelength output optical parametric amplification laser system. Background technique [0002] The rapid development of femtosecond lasers in recent decades has provided humans with unprecedented practical means and development opportunities for fully exploring microscopic ultrafast phenomena and studying strong field physics. The interaction between high-energy single-cycle pulses and matter can generate tens or even hundreds of orders of higher harmonics. When the pulsed light of the pump reaches the period level, it can output continuous higher harmonics, and the higher harmonics of the continuum spectrum A single attosecond (10 -18 s) pulses, which allow the detection of faster material dynamics processes, such as the movement of electron...

[0005] In the article "Characterization of a high-energy self-phase stabilized near-infrared parametric source" (J.Opt.Soc.Am.B / Vol.25, No.7 / July 2008), C.Vozzi et al. The filament is broadened, and then the infrared spectrum is generated by generating different frequency components (different frequency generation: DFG). After two-stage opa amplification, the infrared cep stable laser source is obtained, but because the DFG process is limited by the spectrum of the filament broadening, the output laser is tuned not very wide
