1High-gain 87 cm<sup>-1</sup> Raman line of KYW and its impact on continuous-wave Raman laser operation.

Sarang S, Williams RJ, Lux O, Kitzler O, McKay A, Jasbeer H, Mildren RP.

Opt Express. 2016 Sep 19;24(19):21463-73. doi: 10.1364/OE.24.021463.

We report a quasi-continuous-wave external cavity Raman laser based on potassium yttrium tungstate (KYW). Laser output efficiency and spectrum are severely affected by the presence of high gain Raman modes of low frequency (< 250 cm<sup>-1</sup>) that are characteristic of this crystal class. Output spectra contained frequency combs spaced by the low frequency modes but with the overall pump-to-Stokes conversion efficiency at least an order of magnitude lower than that typically obtained in other crystal Raman lasers.
