Broadly tunable oscillator-amplifier system using lithium (F(2)(+))A centers in KCl.
An oscillator-amplifier system has been constructed using (F(2)(+))(A) centers in KCl:Li crystals and a 1.41-microm laser pump generated by Raman shifting a 1.06-microm 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-microm spectral wavelength range.
