Raman lasers based on bulk diamond are a valuable resource for generating coherent light in wavelength regimes where no common laser diodes are available. Nevertheless, the widespread use of such lasers is limited by their high threshold power requirements on the order of several Watts. Using on-chip microresonators, a significant reduction of the lasing threshold by more than two orders of magnitude has been shown. However, these resonators lack a continuous tuning mechanism and, mainly due to…

On-Chip Diamond Raman Laser
Synthetic single-crystal diamond has recently emerged as a promising platform for Raman lasers at exotic wavelengths due to its giant Raman shift, large transparency window and excellent thermal
A continuous-wave Raman silicon laser
The demonstration of a continuous-wave silicon Raman laser is demonstrated and it is shown that TPA-induced FCA in silicon can be significantly reduced by introducing a reverse-biased p-i-n diode embedded in a silicon waveguide.
A cascaded silicon Raman laser
One of the major advantages of Raman lasers is their ability to generate coherent light in wavelength regions that are not easily accessible with other conventional types of lasers1. Recently,
A single-frequency intracavity Raman laser.
A continuous-wave (CW) single-longitudinal-mode (SLM) intracavity Raman laser is demonstrated for the first time, by virtue of the spatial hole-burning free nature of stimulated Raman scattering (SRS) gain, to provide a new approach to SLM laser operation with good simplicity and power dynamic range.

Ultralow-threshold Raman laser using a spherical dielectric microcavity
This work demonstrates a micrometre-scale, nonlinear Raman source that has a highly efficient pump–signal conversion (higher than 35%) and pump thresholds nearly 1,000 times lower than shown before, which represents a route to compact, ultralow-threshold sources for numerous wavelength bands that are usually difficult to access.

With a highly coherent, optically addressable electron spin, the nitrogen vacancy (NV) centre in diamond is a promising candidate for a node in a quantum network. However, the NV centre is a poor
