Solid-state Red Laser with a Single Longitudinal Mode from Carbon Dots.

Angewandte Chemie, 2021
Miniaturized solid-state lasers with a single longitudinal mode are vital for various photonic applications. Here we prepare red-emissive carbon dots (CDs) with a photoluminescence quantum yield (PLQY) of 65.5% by combining graphitic nitrogen doping and ...

Random-wavelength solid-state laser

Optics Letters, 2004
The spectral properties of a diode-pumped Yb:Y2O3 ceramic laser are reported. We show experimentally that the instantaneous emission wavelengths of the laser change randomly with time, whereas its emission has fixed well-defined transverse modes. The central wavelength of the laser emission also shifts prominently with the increase of intracavity light

Festkörperlaser (solid state lasers)

1989
Das aktive Medium der konventionellen Festkorperlaser besteht aus Kristallen oder Glasern mit Abmessungen von einigen cm, welche mit optisch aktiven Ionen dotiert sind. Es handelt sich dabei meist um Ionen der Uebergangsmetalle wie z.B. Cr3+ oder der seltenen Erden wie z.B. Nd3+ oder Ho3+.

Composite ceramic with high saturation input powder in solid-state laser lighting: Microstructure, properties, and luminous emittances

Ceramics International, 2018
Solid-state laser lighting produced by blue laser diode (LD) and yellow-emitting phosphor converter materials is an exciting new development. The great flux from the laser diode results in self-heating, which lead to high temperature, thus new phosphor ...
