But producing a small spot size with blue light has been tricky, says Hiroshi Ohno, who manages the laser development team to which Hagino belongs. A high brightness laser beam requires both high ...

In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other ...

Australian laser company BluGlass has received an order of around $760,000 for semi-custom GaN laser diode bar products, from ...

With a diameter of just 300 micrometers, these generate a blue laser beam with a wavelength of 450 nanometers. A phosphor converter transforms this into roadworthy white light with a color ...

A semiconductor laser that emits light in the 400-450 nm range. Although it was very difficult developing blue lasers, which emit smaller wavelengths than other colors, blue lasers became ...

Laser manufacturer BluGlass (ASX:BLG) has received an A$120,000 order for its semi-custom Gallium Nitride (GaN) laser diode ...
