“…The first room temperature lasing in LiF:F 2 crystal plate was obtained by Gusev et al [16] Broadband spectrally nonselective laser oscillations at the wavelengths near λ e ≈ 0.67 µm were observed under nanosecond pulsed dye laser excitation at 0.436 µm. The LiF:F 2 laser medium was then studied in a number of subsequent works [17][18][19][20][21]. The bleaching effect severely limits the laser action of F 2 CCs to about several tens -hundred pulses at any fixed position within the sample depending on the parameters of the pump laser and LiF:F 2 crystal characteristics [17,19].…”

The inherent feature of LiF:F 2 CCs is that their high concentration allows one to produce a distributed feedback CCs laser by direct writing in a medium a permanent Bragg grating using a mode-locked titanium sapphire femtosecond laser [20,21].…”

Active media composed of the particles of solid-state laser materials are the subject of a significant number of studies since this approach can provide new solutions to the problem of heat removal from the laser medium. Powder from LiF crystal particles with F2 color centers (sized up to 1000 µm) immersed in a mixture of heptane and vaseline oil (forming an index-matched slurry) was examined as an active medium in a test experiment under Coumarin 120 dye laser pumping. The pulses of collimated radiation (beam divergence 2–5 × 10−3 rad) in the spectral region near 0.68 µm with duration about 10 ns and energy near 0.1 mJ were obtained at the output of the resonator containing a glass cuvette with the LiF:F2 slurry. Laser action of the active medium in the form of a slurry is reported for the first time to our knowledge. Further research of the slurry laser on crystal or glass particles is discussed.
