✦ Synopsis

Monoclinic Y 2 SiO 5 was found to be an attractive, simultaneously laser and χ (3) -nonlinear active optical crystal. Passively Q-switched LD-pumped nanosecond Nd 3+ :Y 2 SiO 5 self-Raman laser, operating by nonlinear-cascaded scheme is reported. We achieved also quasi-CW generation of Y2SiO5:Nd 3+ at 1.3585 μm. Many-wavelength Raman-induced χ (3) -lasing in undoped Y 2 SiO 5 under picosecond excitation has been observed, as well. All recorded Stokes and anti-Stokes components were identified and attributed to SRS-promoting vibration modes. Gives a short review of self-Raman lasers and laser potential of rare-earth C 6 2h -monoclinic orthosilicates doped with Ln 3+ lasants.
