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 breeze, and no ...

Comparison of a 5W laser, 10W, and 20W diode laser. All these machines have their pros and their cons, but this is a quick comparison of their ability to cut and engrave. I do not have a lot of ...

Ultraviolet-B (UV-B) semiconductor lasers are highly sought for medical, biotechnology, and precision manufacturing ...

Japanese firm Nuvoton Technology has started mass production of its high-power UV semiconductor laser (379 nm, 1.0 W), which ...

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 development of power diode pump laser sources that demonstrate extended life and higher brightness have resulted in this novel technology becoming commercially feasible. This effect prevents ...

A semiconductor-based laser used to generate analog signals or digital pulses for transmission through optical fibers. Both laser diodes and LEDs (light-emitting diodes) are used for this purpose, but ...

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 ...

Surface acoustic wave (SAW) filters already fill our mobile devices, but a new breakthrough finds a way to make them smaller, potentially leading to even more compact devices.

Engineers have learned how to create tiny earthquakes on a microchip—and it could change how smartphones are built. Engineers ...

Laser is of prime importance in Optical memories, Fiber optic communications, Military applications, Surgical procedures, CD players, Printers etc. Various forms of lasers like Gallium Arsenide laser, ...
