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 ...

Since their invention in 1962, semiconductor diode lasers have revolutionized communications and made possible information storage and retrieval in CDs, DVDs and Blu-ray devices. These diode lasers ...

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 ...

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 ...

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, ...

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 ...

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 ...

Since their invention in 1962, semiconductor diode lasers have revolutionized communications and made possible information storage and retrieval in CDs, DVDs and Blu-ray devices. These diode lasers ...
