Abstract

The invention discloses a mid-infrared femtosecond fiber laser light source system. Among them, the system includes: a passive mode-locked optical fiber oscillator, which is configured as a dispersion management cavity, and is used to output high-order soliton pulses with positive chirp; a polarization mode dispersion controller, connected to the passive mode-locked optical fiber oscillator through an optical fiber, used It is used to apply polarization mode dispersion to the high-order soliton pulse for dispersion modulation, and output the dispersion-modulated high-order soliton pulse; the fiber amplifier is connected to the polarization-mode dispersion controller through an optical fiber to amplify the dispersion-modulated high-order soliton pulse and compression operation to realize the conversion of dispersion-modulated high-order soliton pulses to Raman soliton pulses; tellurium-based soft glass optical fibers are connected to fiber amplifiers through optical fibers to translate Raman soliton pulses to the mid-infrared band to obtain mid-infrared Tunable femtosecond Raman soliton pulses in the infrared. The invention solves the technical problem of low Raman soliton conversion efficiency.

Description

technical field [0001] The invention relates to the field of lasers, in particular to a mid-infrared femtosecond fiber laser light source system. Background technique [0002] Tunable high-energy mid-infrared femtosecond pulses have important application value in many fields such as biomedicine, biological imaging, mid-infrared nonlinearity, optical precision measurement, special gas detection, and material precision processing. At present, high-energy mid-infrared femtosecond pulses are mainly obtained by optical parametric oscillation (OPO / OPA), specific wavelength mid-infrared crystals (Fe:Znse, Cr:Znse) or soft glass fibers doped with erbium / thulium ions. Its acquisition method is complicated, the system is huge, the operation is difficult, and the cost is high. It is not suitable for large-scale promotion in many fields, which limits the application of mid-infrared femtosecond pulses in many fields. In recent years, with the development of nonlinear fiber optics, the r...
