As with most IR lasers, it's possible to engrave in colour by adjusting the wavelength. However, the actual results can be ...

"A ridge in the slow-axis direction gives these laser diodes a structure for trapping light in the basic mode," said Mönchmeier. "Since this ridge-type laser diode requires once-only crystal growth ...

Rarely a week goes by that some company doesn’t offer to send us their latest and greatest laser. You know the type — couple of aluminum extrusions, Class 4 diode flopping around in the… ...

In any case, the structure worked. They report laser emission for colors between 520 and 531nm, which is pretty much dead center on the green color required for display technology.

Renesas Electronics has announced the company's first Blue Violet semiconductor laser diode with a wavelength of 405nm and a new structure incorporating an optical waveguide into the semiconductor ...

The realization of semiconductor laser diodes on Si substrates would permit the creation of complex optoelectronic circuits, enabling chip-to-chip and system-to-system optical communications.

Key temperature-dependent characteristics of AlGaN-based UV-C laser diode and demonstration of room-temperature continuous-wave lasing. Applied Physics Letters , 2022; 121 (22): 222103 DOI: 10. ...

A research group led by 2014 Nobel laureate Hiroshi Amano at Nagoya University's Institute of Materials and Systems for Sustainability (IMaSS), Japan, in collaboration with Asahi Kasei Corp., has ...
