Laser-Wakefield Accelerators (LWFA) use the interaction of intense and short-pulse lasers with plasmas to create relativistic high-amplitude plasma density waves. These waves are able to sustain electric fields of GV/cm leading to compact relativistic electron sources. The electron energy gain can be significantly enhanced by propagating the laser in a plasma channel with a parabolic radial density...
We demonstrate a mid-infrared source tunable from 6.7–12.7 μm via difference frequency generation in orientation-patterned GaAs, with 1.3 mW average output power. The input pulses are generated from a femtosecond Tm-doped-fiber laser system.
We demonstrate a 500 MHz ultra-low noise 58fs Tm fiber soliton laser based on carrier phase noise reduction with an electro-optic graphene modulator. The system is used for pumping a doubly resonant OP-GaAs OPO for coherent mid IR generation.
We demonstrate a coherent 2-μm Tm fiber laser frequency comb with a self-referenced carrier envelope offset frequency by performing octave-spanning supercontinuum generation in a periodically poled LiNbO3 waveguide.
