The project describes the operation of a cheap keychain lasers that are being sold in low price. In theory, most common laser heads contains two semiconductors inside which includes a laser diode (LD) ...

Range finders are used for a wide range of tasks, from measuring the distance to an object a few feet away to the distance between the moon and the earth. They work by sending a group of energy pulses ...

Abstract: In this paper a design for a laser diode driver circuit is presented. The International Modern Pentathlon Union (UIPM) has replaced the air pistol with laser pistol for shooting and has ...

A single laser-diode driver from Elantec Semiconductor directly drives both CD and DVD lasers, simplifying the task of combining these optical drives in a single system. Elantec's patented EL629XC ...

FORT COLLINS, Colo.--(BUSINESS WIRE)--IXYS Corporation (NASDAQ IXYS), a leader in power semiconductors for power conversion and motion control applications, announced today that its Colorado division ...

Ricoh Electronic Devices has expanded its portfolio with the addition of two new Laser Diode Driver ICs targeted for laser scanning type automotive and consumer projector applications. Laser driven ...

MILPITAS, Calif.--(BUSINESS WIRE)--SiliconCore Technology, a leading fabless analog products company, today announced that the US Patent Office has approved its patent application for “Higher ...

Touted as the market's lowest-power laser diode driver, the MAX3930 is designed to directly modulate laser diodes at data rates up to 10.7 Gb/s while drawing only 108 mA from a single +5V or -5.2V ...

The new laser diode driver iC-HT permits microcontroller-based activation of laser diodes in CW mode. With this device laser diodes can be driven by either the optical output power (using APC), the ...

See this diagram,I've been told the the proprietary drivers offer some extra protection from very short spikes (on power up and shutdown) in the current which laser diodes are very sensitive to and ...
