A Zero Threshold Raman Laser refers to a type of laser based on the Raman scattering effect allowing highly efficient light generation with very low power requirements.

What was the impact of your first continuous-wave silicon Raman laser? When we started working on the silicon laser two years ago, we took a different route. Most people had attempted to create a ...

Writing in Optics Letters, David Spence and his co-workers from Macquarie University in Australia report the first picosecond pulse, mode-locked diamond Raman laser emitting at 573 nm (ref.

Braud and colleagues report that several approaches are currently being investigated in a bid to meet the challenge, for example using complex combinations of crystals in Raman laser designs, or by ...
