Abstract :
We present a scheme for dual-wavelength operation of a diode-pumped Cr3+:LiCaAlF6 (Cr3+:LiCAF) laser with tunable frequency difference based on external optical feedback from a Littman-mounted diffraction grating. The maximum spectral separation achieved allows a frequency separation from 0 to 9 THz in the 785 nm region.
