High-power direct-diode lasers have emerged as a competitive option for applications like cladding, welding and heat treating. Stuart Woods of Coherent explains why the basic construction and ...

The basis of a solid-state diode laser is, of course, the diode. Laser diodes can have different emission wavelength—most of them have between 405 nm to 808 nm. The diodes usually have TO3, TO5, TO9, ...

Efficient 1.5 W CW and 9 mJ quasi-CW TEM00 mode operation of a compact diode-laser-pumped 2.94 µm Er:YAG laser Sheaumann has developed the first commercially available diode-laser-pumped continuously ...

In the autumn of 2003 the US Department of Defense launched an ambitious program to create diode lasers that are 80% efficient at converting electricity into light. Dubbed SHEDS (standing for ...

JDS Uniphase, a major supplier of optoelectronic components to the telecoms sector and other industries, is now offering a new series of high-power fibre-coupled laser diodes for pumping fibre lasers, ...

Last August, the town of Irondequoit, N.Y., near Rochester, opened its $13 million, 37,800-sf public library. The entry lobby is illuminated by organic light-emitting diode (OLED) fixtures, one of the ...

Laser diodes can destroy themselves in a few nanoseconds, so testing the response and stability of a feedback-stabilized laser-diode driver can be expensive. The simulator circuit in Figure 1 shows a ...

Scientists have incorporated meticulously engineered colloidal quantum dots into a new type of light emitting diodes (LEDs) containing an integrated optical resonator, which allows them to function as ...

Laser cutting and engraving technologies have become essential tools across a wide variety of different industries, from manufacturing, art and small businesses. These technologies use laser beams to ...

Ultraviolet-B (UV-B) semiconductor lasers are highly sought for medical, biotechnology, and precision manufacturing applications; however, previous UV-B laser diodes were limited to pulsed operation ...
