Efficient room temperature LiF:F2+ * * color center laser tunable in 820-1210 nm range

Academic Article

Abstract

  • Efficient room temperature operation of a LiF:F2+ * * color center laser at record levels of output energy (up to ∼ 100 mJ) and average power (up 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 F2+ * * color centers and (ii) appropriate choice of the pumping laser wavelength. Record real efficiencies for LiF:F2+ * * laser, 28% under pumping by radiation of an alexandrite laser (740 nm) and 53% under pumping by Raman shifted (H2 and D2) second harmonic of a Nd:YAG laser (683 and 633 nm), were achieved. © 1998 Elsevier Science B.V.
