Tunable lasing at around 405 nm is realised with an InGaN device featuring a narrow-ridge active channel and a periodically ...

Pictured above: artistic rendering of visible DFB laser diodes in TO-can packages. a) Typical continuous-wave characteristics (power-current-voltage) of DFB LD at 450 nm. b) Spectra of DFB LDs with ...

As a proof of concept, we tested a 405 nm laser diode with a beam ellipticity of 2.37. Simulations predicted a coupling efficiency of ~80%, and we achieved 67% experimentally. Additionally, we ...

Including pulsed-dye lasers (PDL), intense pulsed light (IPL), neodymium-doped yttrium aluminum garnet (Nd:YAG) lasers, diode lasers, and others, non-ablative laser resurfacing tends to cause fewer ...
