An oscillator–amplifier system has been constructed using (F2+)A centers in KCl:Li crystals and a 1.41-μm laser pump generated by Raman shifting a 1.06-μm Nd:YAG line in liquid nitrogen. Output energies of 2.3 mJ and peak powers exceeding 0.4 MW were achieved. The system was tuned continuously over the 2.0–2.4-μm spectral wavelength range.
