E. Munin et al., BROAD-BAND, INTENSITY-DEPENDENT ABSORPTION IN TETRAVALENT CHROMIUM-DOPED CRYSTALS, Applied physics letters, 63(13), 1993, pp. 1739-1741
Cr4+ -doped Y2SiO5 and Ca2Al2SiO7 have been investigated as broadband,
solid state saturable absorbers. Saturation properties in the near in
frared as well as a demonstration of tunable, passive Q switching of a
flash-lamp pumped Cr:LiSAF laser are discussed.
