OPTISWITCH TECHNOLOGY ANNOUNCES NEW 120 AMP DUAL CHANNEL PULSED LASER DIODE DRIVER

(San Diego, CA - March 31, 2010) OptiSwitch Technology Corporation (OTC) is pleased to announce the availability of a new compact, pulsed laser diode driver capable of independently driving two laser diode bar stacks. The PLDD-120-10-20D is a dual-channel laser diode driver ideal for applications where the user needs to switch between two diode pumped laser sources - for example an integrated laser rangefinder and laser marker/target designator. Switching the output of the PLDD-120-10-20D is achieved by simply toggling a digital signal input. This insures that both channels cannot be fired simultaneously. Each channel of this unit is capable of driving a 10 bar stack to 120 amps with a 300 μs pulse. The repetition rate at this level is 20 Hz; however, increased repetition rates can be achieved at either reduced currents or pulse widths. Conversely, higher peak current can be achieved at reduced pulse widths. The driver’s small footprint (2.2" x 2.2" x 0.86") and light weight (2.24 oz) makes it ideal for hand-held applications.

OptiSwitch Technology Announces Two New Pulsed Laser Diode Drivers

(San Diego, CA - January, 19, 2010) OptiSwitch Technology Corporation is proud to announce the availability of two new ultra compact pulsed laser diode drivers for man-portable target designation, rangefinding, illumination, and remote sensing: the PLDD-200-1-1 and the

PLDD-300-1-20.

The PLDD-200-1-1 is an ultra miniature driver that delivers 200 amps peak current into a single laser diode bar with a maximum pulsewidth of 300µs at 1 Hz. Weighing only 22 grams and measuring 0.75" X 2.69" X 0.91," this versatile little driver ideal for hand held laser systems.

The PLDD-300-1-20 is the first driver of its kind to be made by OptiSwitch - a short pulse, ultra lightweight driver optimized for driving one laser diode bar at high current. This compact driver delivers 300 amps peak current with a minimum pulsewidth of 2 µs, can be operated at up to 20 Hz, and weighs only 12 grams, and measures only 0.75

OPTISWITCH TECHNOLOGY ANNOUNCES NEW COMPACT SHORT-PULSE DIODE DRIVER FOR RANGEFINDING AND REMOTE SENSING APPLICATIONS

(San Diego, CA, August 14, 2009) OptiSwitch Technology Corporation announces a new short pulsed diode driver for rangefinding, remote sensing and defense and security applications. The LDD-50-SP driver is a compact (only 2.7 x 1.3 inches), lightweight (<14 g), and all solid state pulsed current source designed to drive single or multichip laser diodes. At 50 amps of peak current, the PLDD-50-SP delivers <5 ns pulse widths with pulse repetition frequency variable from single shot to 15 KHz. Laser diodes can be either mounted on the edge of the driver or vertically through mounting holes. The diameter and placement of these holes accommodate the most common laser diode packages. This economical driver delivers clean current pulses and a precise current monitor output gives the user real time monitoring of the laser diode current.

OptiSwitch announces new pulsed diode laser driver product for man-portable applications

(San Diego, CA - June 29, 2009) OptiSwitch Technology Corporation (OTC), a world leader in the development and manufacturing of miniature high current pulsed laser diode drivers for defense and commercial applications, today introduced an ultra-compact pulsed 120 amp laser diode driver for man-portable target designation, rangefinding, illumination, and remote sensing.

OTC’s pulser technology was rapidly developed in the past several years with funding in part through highly successful contracts with the US Army, Navy, Air Force, and DARPA. The OTC technology is being commercialized in a series of products that together comprise the PLDD product family. Commercialization of this technology offers defense and commercial customers a cost effective, compact OEM driver with high efficiency and minimal battery consumption. The driver’s peak current, pulse length, and rep rate have been chosen specifically to match the needs of 808nm diode laser bars which are used to pump solid state lasers.

The first in this series, the PLDD-120 delivers 120 amps of peak current for 300 us to a laser diode bar at a 1 Hz repetition rate. The PLDD-120 weighs only 15.2 grams and is only 2.1"x0.75"x0.78" in dimension. It is designed to operate from a single DL123 battery or equivalent.

OptiSwitch Announces Short Pulsed Laser Diode Driver for Rangefinding; Integrated Pulsed Laser Diode to be Demo’d at Upcoming SPIE’s Defense, Security & Sensing Symposium

(San Diego, CA - April 7, 2009) Optiswitch Technology Corporation (OTC), a manufacturer of high current, ultra compact and lightweight pulsed laser diode drivers, announced today the release of its short pulsed laser diode driver, the PLDD-50. The efficient driver is the company’s first commercially available short pulse driver designed for rangefinding, remote sensing, and other defense and security applications.

The new PLDD-50 delivers 50 amps peak current with a <4 ns pulse width (5 nH load) and up to 30 KHz rep rate. The device drives single and multi stack laser diodes in an ultra lightweight and compact footprint. The PLDD-50 can be purchased as a stand alone unit or with an integrated laser diode supplied from the factory. This new driver complements OTC’s existing line of high performance, longer pulse drivers used for pumping solid state lasers.
