Abstract:
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:F2–. These lasers were used in intracavity spectrum analyzers of ~10–7 cm–1 sensitivity in the wavelength range 880–960 nm and ~7×10–8 cm–1 in the range 1.12–1.19 μ.
