“…An example of this is the 1053 nm laser line which is close to the σ-polarized wavelength generated in Nd:YLF. Although the stimulated emission cross-section was much smaller (1/5 of that at 1061.5 nm), it was possible to achieve pure CW 1053 nm laser generation in Nd:GYSGG by optimizing the cavity mirror coatings to suppress the oscillation at 1058.4 and 1061.5 nm [25]. The maximum output power was 4.17 W and the optical-optical conversion efficiency reached 33.9%.…”

“…[20] The antiradiation crystal GYSGG doped with Nd 3+ shows an excellent dual-wavelength laser characteristic. [21][22][23][24] Besides, a high-power 2.79 µm wavelength output can be realized in the YSGG crystal doped with Er 3+ ions. [25] In further, the pure crystals such as YSGG and GYSGG can also be thermally bonded as endcapping to improve the laser performance of YSGG/Er:YSGG and GYSGG/Er,Pr:GYSGG composite crystals.…”

“…Taking advantage of stimulated Raman scattering (SRS) effect of YVO 4 crystal, [ 13 ] multiple wavelength lasers including fundamental and Raman lasers oscillating simultaneously have been developed [ 14 ] with actively Q‐switching and passively Q‐switching technology, [ 15,16 ] which have a wide range of applications in the fields of space optical communication, [ 17 ] laser sensing, [ 18 ] digital holography technology, [ 19 ] and nonlinear frequency conversion. [ 20 ] In particular, the small‐spaced dual‐wavelength laser has been used to generate terahertz waves through difference frequency, [ 21 ] which have been widely used in human medical imaging and biological detection. [ 22 ] Compact eye‐safe 1525 nm actively Q‐switched Nd:YVO 4 self‐Raman laser has been converted from 1342 nm fundamental laser with 890 cm −1 Raman shift line.…”
