End-Pumped Intracavity Solid State Raman Lasers

Alkali metal impact on structural and phonon properties of Er3+ and Tm3+ co-doped MY(WO4)2 (M = Li, Na, K) nanocrystals

“…1 They also exhibit strong stimulated Raman scattering due to large third-order electric susceptibility, 2,3 and possess a great ability to accommodate various rare earth ions. 4 All these features make them promising materials for solidstate laser applications. [1][2][3][4] In recent years, growing interest has also been focused on developing synthesis methods of micro-and nanosized double tungstates since these materials in powder form appeared to be promising phosphors for visual displays and solid-state lighting.…”

Efficient high-output diode side-pumped electro-optical Q-switched Nd:YAG/KGd(WO4)2Raman laser with conductive and air cooling

“…Some important Raman crystals include Ba(NO 3 ) 2 [5], LiIO 3 [6], YVO 4 [7], and tungstates [8][9][10][11] such as KGd(WO 4 ) 2 , BaWO 4 , SrWO 4 , etc., among which KGd(WO 4 ) 2 is very promising, due to its favorable thermal and mechanical properties [12]. Near infrared Raman lasers based on tungstates have been proven to be efficient and reliable [8,13], in various resonator configurations, such as external cavity [14,15], intracavity [16][17][18], and coupled cavity [19]. In addition, self-Raman laser configuration has own advantages due to low intracavity losses and simple laser design.…”
