  • Fiber-Coupled Diode Laser Bar
Mar 2008
DILAS Diodenlaser GmbHRequest Info
MAINZ, Germany, March 3, 2008 -- With a new module that delivers up to 50 W of continuous-wave (CW) power at 808 and 976 nm, Dilas Diodenlaser GmbH said it is raising the bar for high-quality, high-power, single-bar-based fiber-coupled diode laser modules.

The module is the latest addition to Dilas' fiber-coupled diode laser line, delivering its power through a 400-µm SMA fiber with a numerical aperture of  less than 0.22, making it the most reliable and highest-performing diode laser available today, the company said. The fiber-coupled diode laser module is primarily intended for end-pumping of solid-state laser materials for fiber lasers, as well as for medical applications.

DilasFiber-CoupledLaserBar.jpgMeasuring less than 100 x 31 x 20 mm (L x W x H), this industry-standard package features a wall-plug efficiency greater than 35 percent and features a typical spectral width of less than 4 nm, FWHM (full width half maximum). The laser power from the module is delivered via a detachable single-core fiber, which is terminated with a standard SMA 905 connector, Dilas said.

The high-power fiber-coupled diode laser modules are based on a single laser diode array and are available in an overall height of less than 30 mm including optional features such as integrated pilot beam, power monitor, fiber detection sensor, user-exchangeable protection window, and temperature sensor, according to Dilas.

1. A bundle of light rays that may be parallel, converging or diverging. 2. A concentrated, unidirectional stream of particles. 3. A concentrated, unidirectional flow of electromagnetic waves.
A two-electrode device with an anode and a cathode that passes current in only one direction. It may be designed as an electron tube or as a semiconductor device.
fiber laser
A laser in which the lasing medium is an optical fiber doped with low levels of rare-earth halides to make it capable of amplifying light. Output is tunable over a broad range and can be broadband. Laser diodes can be used for pumping because of the fiber laser's low threshold power, eliminating the need for cooling.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
