High Power Sub-Picosecond Pulsed SWIR Source Based on Thulium Assisted Raman Wavelength Shifting

We demonstrate 1.5W sub-picosecond pulsed source near 2μm. Cavity-less source is based on integrated association of 3rd order Raman wavelength-shifting and thulium amplification. Coherent spectrum of 61.5nm with 49% pump power conversion efficiency is achieved.
