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

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 ...

Epson has expanded its home cinema range with two "4K Pro-UHD" laser projectors, the EH-QS100W and EH-QS100B. Both promise to deliver high-end viewing experiences with the convenience of ...

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 ...

In a new study, researchers used lasers to uncover highly intricate designs of ancient tattoos on mummies from Peru. The preserved skin of the mummies and the black tattoo ink used show a stark ...

Last summer, additional details emerged regarding the Peresvet ground-based laser system, which was designed for more than shooting down drones. Rather, the platform is being developed to emit ...

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 ...

During the peer-review process the editor and reviewers write an eLife assessment that summarises the significance of the findings reported in the article (on a scale ranging from landmark to useful) ...
