OSRAM Opto Semiconductors is expanding its range of high-power lasers.
In addition to discrete power laser diodes and unmounted laser bars, there will be water-cooled vertical laser stacks and laser bars in standard packages. This semiconductor specialist will therefore be offering a wide range of power laser diodes from a single source, taking the shortest possible route to the customer. The new laser diodes will be presented at the Photonics West fair in San José, USA from January 23 to 25, 2007.
Water-cooled vertical laser stacks consist of up to 20 laser bars which operate in continuous wave (cw) mode or in quasi-continuous wave (qcw) mode. Their standard wavelengths are 808, 915, 940 or 975 nm. Depending on the version, the stacks can achieve outputs in the kilowatt range and have a life of more than 10,000 hours. Typical applications include high-output systems for pumping solid-state lasers, direct material processing and medical engineering.
Passive cooled laser diodes on solid copper heat sinks (CS mounts) are used wherever water cooling is not possible, for example in transportable systems for medical applications. They provide optical outputs of up to 50 W in continuous wave mode.
As a specialist in laser technology, OSRAM Opto Semiconductors uses the latest generation of laser bars. With its extensive and ever growing portfolio of products with different wavelengths and outputs, the company can react promptly to the rapidly changing demands of the market. Power laser diodes will be of modular design and available in different standard versions. Application-specific versions can also be provided as required.
