WILSONVILLE, Ore., April 29, 2015 — Flir Systems VPowrFlir Systems Inc. has announced a high-power, short-pulse laser diode with electronics designed for applications including lidar, gesture recognition and 3-D sensing.

The VPowr laser source is based on the company’s proprietary vertical-cavity surface-emitting laser (VCSEL) technology. VCSELs are brighter and more efficient than traditional LED-based systems and provide improved eye safety. They also offer superior illumination in terms of uniformity and speckle noise over commonly used edge-emitting lasers.

Capable of more than 50-W peak power from 10- to 50-ns pulses out of a single aperture, the diode operates at an emission wavelength of 940 nm.

The device is available on a fully integrated, compact driver circuit board for easy interface and operation. A bare chip on a submount is also an option for customers conducting their own on-board integration.

VPowr is an ITAR-restricted product, but custom chip development is available to approved parties.


GLOSSARY
lidar
An acronym of light detection and ranging, describing systems that use a light beam in place of conventional microwave beams for atmospheric monitoring, tracking and detection functions. Ladar, an acronym of laser detection and ranging, uses laser light for detection of speed, altitude, direction and range; it is often called laser radar.
