Feasibility of radiation wavefront correction in the case of pulsed operation of a laser with a plane–plane resonator

Nonlinear Optical Spectroscopy of Ce³⁺ Ions in Insulating Crystals

“…Equation (4.34) gives a value of gR = 1.9 cm/GW for the 992cm• 1 vibration in benzene in the visible region (N = 7 X 10 21 cm• 3 , rJ2rr.c = 1.2 cm• 1 , CJ = 2.7 X 10• 28 at ffis /2rr.c = 21000 cm• 1 [72]). For the 1085 cm• 1 vibrational mode in a calcite (CaC0 3 ) crystal, a measurement of the Raman gain gave 13 cm/GW [116]. Thus, the calculated electronic Raman gain in CeF 3 at low temperature is several times smaller than vibrational Raman gain in common materials.…”

Efficient Diode-End-Pumped Actively Q-Switched Nd:YLF/SrWO 4 Raman Laser

“…Laser beam conversion using stimulated Raman scattering (SRS) is an important process for addressing the lack of practical lasers in wavelength regions away from the wavelengths of base laser technologies such as Nd and Yb lasers and their harmonics. Until now, the important Raman crystals for achievement of SRS have comprised nitrates Ba(NO 3 ) 2 , [1,2] calcites CaCO 3 , [1,2] iodates LiIO 3 , [3,4] molybdates SrMoO 4 and CaMoO 4 , [5] vanadates YVO 4 and GdVO 4 , [6−8] tungstates KGd(WO 4 ) 2 , BaWO 4 , SrWO 4 , and PbWO 4 , [9−12] and diamond. [13] Among these crystalline Raman crystals, SrWO 4 has been regarded as an excellent Raman-active crystal for its good mechanical and optical properties, as well as a comparatively high Raman gain coefficient for a wide range of pump pulse duration from picoseconds to nanoseconds.…”
