Eye-safe actively Q-switched diode-pumped lasers with intracavity Raman conversion in YVO4, KGd(WO4)2, PbWO4, and Ba(NO3)2 crystals

Optimization of an intracavity Q-switched solid-state second order Raman laser

“…where ; R 1 , R 2 are reflectivity of input and output coupler; L l , L s is the loss of cavity for fundamental laser and Stokes; L Q is the AO Q-switch loss, according to Dashkevich [15], it can be calculated as (3).…”

Anisotropic Raman spectral analysis and laser output based on large-sized scheelite bismuth molybdate tungstate mixed crystals

“…Employing Ba(NO 3 ) 2 as Raman crystals, an eye-safe laser output at 1.562 μm and 1.88 μm was successfully achieved, respectively. 8,9 Diamonds as Raman crystals have their own advantages, like a large Raman shift (1332 cm −1 ), superior gain ability (17 cm/GW@1.064 μm) and extremely high thermal conductivity (∼2000 W m K −1 ), and multiwavelength-band Raman laser output has already been achieved. 10,11 Vanadates are currently the most important Raman crystals, and YVO 4 is the outstanding representative.…”

Diode-Pumped Actively Q-Switched Nd:YVO4/RTP Intracavity Raman Laser at 1.49 µm

“…Stimulated Raman scattering, as an efficient method for laser frequency conversion, is quite promising for generating radiation in the eye-safe spectral region, because of the availability of suitable pumping laser and Raman crystal with required Raman frequency shift. Thus far, many different wavelengths have been successfully generated by using different Raman crystals, such as nitrates (Ba(NO 3 ) 2 ) [4][5][6], vanadates (YVO 4 , GaVO 4 ) [7][8][9], and tungstates (KLu(WO 4 ) 2 , BaWO 4 , SrWO 4 ) [10][11][12].…”
