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 ...

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 ...

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, ...

The High-Repetition-Rate Advanced Petawatt Laser System (HAPLS) under construction in the Czech Republic is designed to generate a peak power of more than 1 quadrillion watts (1 petawatt, 10 15 watts) ...

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 ...

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 ...

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 ...

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, ...

As anyone who has used an FDM printer can tell you, it’s certainly not the magical replicator it’s often made out to be. The limitations of the platform are numerous — ranging from anisotropic ...
