Description

Ultra wide band optics coherence tomography Chirp pulse amplification laser system
Technical field
The present invention relates to laser field, more particularly to a kind of ultra wide band optics coherence tomography Chirp pulse amplification laser system, its It is primarily adapted for use in ultra wide band laser system, optics coherence tomography laser system, monocycle laser system, joule level high energy monocycle laser System.
Background technology
High-energy monocycle (~3fs) laser pulse is one of forefront of current international laser technical research.2009 Gunther Krauss etc. are by two-way is homologous but femtosecond fiber Laser coherent combining of different-waveband generates that to receive joule 4.3fs mono- Periodic laser pulse (Gunther Krauss, et.al.Synthesis of a single cycle of light with compact erbium-doped fibre technology,Nature photonics,Vol 4,pp33,2010.)。2011 Year Shu-Wei Huang etc. is homologous but optically erasing Laser coherent combining of different-waveband generates the 15uJ monocycles by two-way Interior laser pulse (Shu-Wei Huang, et.al.High-energy pulse synthesis with sub-cycle waveform control for strong-field physics,Nature photonics,Vol 5,pp 475, 2011.).Although above two method achieves monocycle laser pulse, single pulse energy very little, main cause includes:
1. above two method is to carry out high power arteries and veins in optics coherence tomography, therefore transmission medium to transfer limit short pulse The nonlinear effect and dielectric damages threshold restriction of punching composite pulse energy lift;
2. above two method is that the optics coherence tomography of two pulses is realized using double color plate, therefore high power transmitted light Nonlinear effect and double color plate damage threshold limit composite pulse energy lift.
The enterprising line frequency domain subrane of Fourier plane in the 4f systems based on grating such as Bruno E.Schmidt in 2013 Optically erasing avoids Gain-narrowing effect, simultaneously because Fourier transform limited pulses broadening improves the pulse of amplification Energy, generates 1.43mJ binary cycles laser pulse (Bruno E.Schmidt, et.al.Frequency domain optical parametric amplification,Nature communications,ncomms4643,2014.).The party Although method by the energy lift of cycle stage laser pulse to millijoule level, be difficult be promoted to again joule, several joules, even Tens of joules of levels.Main cause is amplified for this method in Fourier plane to different frequency band pulse, per band frequency The limited bandwidth of wave band avoids the gain narrowing of amplification medium, while the time pulsewidth of broadening reduces nonlinear effect, carried High damage threshold.But if the bandwidth further reduced per band frequency wave band needs very highdensity grating, and it is very big The concave mirror of bore and very long-focus, thus system scale will be extremely huge and become infeasible.
