InGaN-LD-Pumped ${\rm Pr}^{3+}$: ${\rm LiYF}_{4}$ Continuous-Wave Laser at 915 nm

IEEE Photonics Journal, 2014
We demonstrate the first InGaN-LD-pumped room temperature and continuous-wave laser operation of a Pr3+: LiYF4 crystal at 915 nm. A maximum output power up to 78 mW with a laser slope efficiency of about 17% is obtained. The round-trip optical losses are

Generation of a 578-nm Yellow Laser by the Use of Sum-Frequency Mixing in a Branched Cavity

IEEE Photonics Journal, 2016
A compact, continuous-wave, solid-state laser at 578 nm has been demonstrated, for the first time to our knowledge, by use of intracavity sum-frequency mixing from a branched cavity with an LBO crystal. Two gain mediums, namely, the Nd:YAG single crystal

Keldysh Green's function approach to coherence in a non-equilibrium steady state: connecting Bose-Einstein condensation and lasing

, 2010
Solid state quantum condensates often differ from previous examples of condensates (such as Helium, ultra-cold atomic gases, and superconductors) in that the quasiparticles condensing have relatively short lifetimes, and so as for lasers, external ...
