摘要：

Efficient room temperature operation of a LiF:F-2(+**) color center laser at record levels of output energy (up to similar to 100 mJ) and average power (up to similar to 1.4 W) with a very wide 796-1210 nm tuning range is described. A photo-and thermostable lasing was realized due to: (i) improved technology of LiF crystals with stabilized F-2(+**) color centers and (ii) appropriate choice of the pumping laser wavelength. Record real efficiencies for LiF:F-2(+**) laser, 28% under pumping by radiation of an alexandrite laser (740 nm) and 53% under pumping by Raman shifted (H-2 and D-2) second harmonic of a Nd:YAG laser (683 and 633 nm), were achieved.
