Broadband lasing and nonlinear conversion of radiation from LiF : F+2 and LiF : F-2 colour centre lasers

Academic Article


  • Broadband LiF:F+2 and LiF:F-2 colour centre lasers are studied theoretically and experimentally. The cavities of these lasers ensure spatial wavelength selection. The lasers generate nanosecond pulses in the near-infrared range with a spectrum wider than 1300 cm-1. As a result of optimisation of the optical layout and selection of proper nonlinear crystals, the broadband laser radiation with a spectral width of more than 1300 cm-1 is efficiently and simultaneously converted into the second harmonic in a nonlinear LiIO3 crystal and into the fourth harmonic, in a nonlinear BBO crystal.
