Raman Lasing in a Tellurite Microsphere with Thermo-Optical on/off Switching by an Auxiliary Laser Diode by Elena A. Anashkina, Maria P. Marisova, Vitaly V. Dorofeev, Alexey V. Andrianov

“…We demonstrated experimentally a robust, simple, and cheap way of thermo-optically controlled on/off switching of Raman lasing in a tellurite glass microsphere by an auxiliary laser diode. With a permanently operating narrow-line pump laser, on/off switching of the auxiliary 405 nm laser diode led to off/on switching of Raman generation. …”

Continuous-wave second-harmonic generation in the far-UVC pumped by a blue laser diode by Eric J. Stanton, Peter Tønning, Emil Z. Ulsig, Stig Calmar, Maiya A. Stanton, Simon T. Thomsen, Kevin B. Gravesen, Peter Johansen, Nicolas Volet

“…Here we present a compact solid-state far-UVC laser source based on second-harmonic generation (SHG) using a low-cost commercially-available blue laser diode pump. Leveraging the high intensity of light in a nanophotonic waveguide and heterogeneous integration, our approach achieves Cherenkov phase-matching across a bonded interface consisting of a silicon nitride (SiN) waveguide and a beta barium borate (BBO) nonlinear crystal. …”
