Abstract

For the first time a continuous-wave, multiwavelength, polycrystalline Cr2+:ZnSe spatially-dispersive laser is described. We show a dual-wavelength operation of the laser, tunable over a 600 nm spectral range (2200-2800 nm), an ultrabroad-band operation of the laser, producing a continuous 135 nm wide spectrum centered at 2500 nm, and show a 200 nm wide (2400-2600 nm) multiline, tunable output spectra, consisting of up to 40 spectral lines. We also show simultaneous tuning of a 20-lines ultrabroadband spectrum over a spectral range of 2200-2800 nm.
