Dual-wavelength Yb: KGW laser with ~1 THz frequency offset

摘要

Dual-wavelength (DW) operation of Yb:KGW laser was demonstrated using a 1 mm-thick BRF. A series of DW pairs with wavelength separation of around 0.5 nm ($Delta u pprox 0.14$ THz) and 4 nm ($Delta u pprox 1.1$ THz) over the range of gain bandwidth were generated.
