Catastrophic optical damage (COD), or catastrophic optical mirror damage (COMD), is a failure mode of high-power semiconductor lasers. It occurs when the semiconductor junction is overloaded by exceeding its power density and absorbs too much of the produced light energy, leading to melting and recrystallization of the semiconductor material at the facets of the laser.

The wavelength of laser diodes is tuned by means of temperature to produce an optimal compromise between the absorption coefficient in the crystal and (lowest possible pump photon energy). High power lasers use a single crystal, but many laser diodes are arranged in strips (multiple diodes n. The basic device structure consists of a rectangular parallelepiped of a direct bandgap semiconductor, usually a III–V compound semiconductor such as GaAs, incorporat-ing a forward-biased, heavily doped p–n junction to provide the optical gain medium in a resonant optical cavity . Solid-state lasers power critical technologies from precision manufacturing to advanced medical systems—but how exactly do they work? Solid-state lasers are made up of key optical and electronic components, with diode pump sources serving as the engine that drives their performance. How is Laser Diode Constructed? Gallium arsenide (GaAs) or indium gallium arsenide (InGaAs) semiconductors are used to build laser diodes.

Two OBIS laser models are available at 505nm, at multiple output power options: The LX model can be digitally modulated up to 150MHz, 500kHz analog. The highly-functional OBIS LS/LX Systems are ideal for scientific, laboratory, and spectroscopic applications. The OBIS Series laser source systems cover the wavelength spectrum from 375nm (Ultraviolet) to 980nm (near-Infrared), and are perfect for flow cytometry and fluorescence spectroscopy. Its design puts an emphasis on compactness, stability and reliability so as to be optimal for the system built-in. The LBX-505 laser The LBX-505 laser diode module is part of the LaserBoxx low noise series of CW DPSS laser and laser diode modules available at a variety of wavelengths from 375nm through 980nm.

The active region of the laser diode is in the intrinsic (I) region, and the carriers (electrons and holes) are pumped into that region from the N and P regions respectively. OverviewA laser diode (LD, also injection laser diode or ILD or semiconductor laser or diode laser) is a device similar to a in which a diode pumped directly with electrical current can create.
