The demonstration of green semiconductor laser diodes with lifetimes of many thousands of hours 1 (similar to that of their blue and red counterparts) holds great promise for the development and ...

The 10W blue diode easily cuts wood, leather, acrylic, and other common materials. Meanwhile, the 2W IR laser can handle fine engraving on metals like anodized aluminum or stainless steel.

Lasers and quantum electronics represent a transformative amalgam of quantum mechanics and electromagnetic technology that underpins much of modern scientific and industrial innovation.

Lundy says those undergoing IPL or laser hair removal “must avoid sun exposure two weeks prior to treatment and two weeks post-treatment, and must wear SPF”. The verdict: IPL and laser devices ...

GaN-based laser diodes (LDs) with different barrier layers are investigated by using simulation and experimental methods. it is found that the absorption loss always decreases with the increasing ...

An InGaN/GaN superlattice (SL) with Mg-doped barriers was designed and inserted into the InGaN-based blue light-emitting diodes (LEDs) as a hole gathering layer (HGL) to promote hole injection into ...

BACKGROUND Inflammatory glaucoma is still a diagnostic and therapeutic dilemma and surgical intervention is always associated with a high risk of failure or reactivation of the inflammatory disease.

The use of exciplex hosts is attractive for high-performance phosphorescent organic light-emitting diodes (PhOLEDs) and thermally activated delayed fluorescence OLEDs, which have high external quantum ...

Over the past few months an increasing number of reports have appeared in the popular press, describing incidents in which individuals claim to have suffered eye injury as a result of misuse of laser ...
