Researchers at Nichia Corporation have demonstrated green InGaN-based lasers grown on c-plane sapphire, with lifetimes capable of supporting commercial applications. The demonstration of green ...

Everyone loves a full-wave bridge rectifier, but there’s no denying that they aren’t 100% efficient due to the diode voltage ...

In a curious historical twist, the “Twelve days of Christmas” are actually the days of revelry that followed the 25th. The ...

The generation of femtosecond optical pulses 1 has opened up a range of applications from real-time monitoring of chemical reactions through to ultrahigh-bit-rate optical communications 2, and has led ...

Abstract: We present a compact and efficient method for directly coupling a near-ultraviolet laser diode with high beam ellipticity to a hollow core fiber (HCF) using an all-fiber mode field diameter ...
