We regularly update news editors and other interested parties with our news ticker. All newsworthy information at LASER COMPONENTS is available here first! You will find the press releases in chronological order below. If you are looking for press releases from a specific department, use the navigation bar on the side. We differentiate between general company news and news from the product groups: photodiodes, IR components, photon counters, lasers, measurement devices, fiber-optical components, optics, and laser accessories.
Coupling Efficiency >85%
LASER COMPONENTS produces pulsed laser diodes with fiber pigtails in Canada. The fibers can be precisely assembled to within just a few µm. This technology allows coupling efficiencies of > 85% to be achieved. Depending on the laser diode chip and fiber core diameter, peak power levels of > 100 W out of the fiber can be reached.
The new pigtailed pulsed laser diodes are available on a standard basis at wavelengths of 905 nm and 1550 nm. The 905 nm PLD delivers 13 W from a 105 µm fiber or 100 W from a 400 µm fiber. Various numerical apertures are available. The 1550 nm PLD delivers 7 W from a 105/125 µm fiber (NA 0.16).
One of LASER COMPONENTS strengths is the ability to develop inexpensive customer-specific solutions.
The new products were developed for applications such as medical or illumination technology where power is required directly at the desired position without any loss caused by additional optics. In laser scanners or in measurement technology, better beam performance is achieved by mixing modes in the fiber. In industry, however, fiber optic technology is used to transmit data across very long distances. Due to their very robust design these diodes can be used in military applications at temperatures between -40°C and +85°C.
