BRIEF COMMUNICATIONS: Quasi-cw lasing of LiF crystals with F2+ and F2- color centers
Quasi-cw operation of color center lasers was achieved and the duration of the output pulses was ~200 μ sec in the case of a LiF:F2+ crystal and ~400 μsec in the case of LiF:. These lasers were used in intracavity spectrum analyzers of ~10−7cm−1 sensitivity in the wavelength range 880–960 nm and ~7×10−8cm−1 in the range 1.12–1.19 μ.
