Yellow picosecond diamond Raman laser [PDF]
2017 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2017 Visible pulsed lasers are required for many applications, for example in biomedical imaging [1] and STED microscopy [2]. Such applications often have stringent requirements on the wavelength and pulse duration, which are not directly available from typical solid-state sources.
