Polariton Laser Diodes [PDF]

Asia Communications and Photonics Conference 2014, 2014
Exciton-polariton lasers are operated in the strong light matter coupling regime. They promise low threshold operation since population inversion is not inherently necessary. Hence they are of great interest for next generation coherent light sources.

Outcome comparison between diode laser pulpotomy and formocresol pulpotomy on human primary molars

Journal of Dental Sciences, 2020
Background/purpose: Diode laser is widely used in dentistry, especially on treating soft tissues. Currently neither the effect of diode laser pulpotomy nor its comparison with formocresol (FC) pulpotomy has been fully investigated.

Intra-cavity frequency doubling of an electrically pumped edge-emitting 980 nm laser diode with PPLN [PDF]

, 2009
The growing trend for laser-based projection displays makes intra-cavity frequency doubling (ICFD) of electrically and optically surface emitting diode lasers in the near IR region become more interesting [1-3].

Optical trapping with superfocused high-M2 laser diode beam [PDF]

, 2015
Many applications of high-power laser diodes demand tight focusing. This is often not possible due to the multimode nature of semiconductor laser radiation possessing beam propagation parameter M2 values in double-digits.

Distributed and Side-Pumped Fiber Laser Using a Laser Diode Bar Stack

IEEE Access, 2018
A distributed, side-pumped Yb3+-doped fiber laser is demonstrated using a laser diode stack as a pump source. Four subwavelength gratings fabricated on the same fused-silica substrate were aligned with four laser diode bars of the laser diode stack ...
