Press Release Summary:
LYDYA(TM) Q-CW and CW laser diode drivers are for single diodes, bars, and stacks, and are available with or without TE temperature controller. Computer controllable devices include diode shunt that remains plugged to diode terminals and short-circuits when diode is not used, output stage designed to avoid transients, and high power circuitry that supplies regulated adjustable current and provides over-current protection.
Original Press Release:
LYDYA(TM) The Laser Diodes Driver Of LASELEC, Now Available In The US !
LASELEC specializes in the design and manufacture of the electronic components for laser systems. Distributed in France and in Europe, LASELEC is proud to announce the launch of LASELEC Inc. in Arlington, Texas, on July 1st, 2004. LASELEC Inc. notably benefits from the large range of LYDYA(TM) high power laser diode drivers and is in charge of the "Lasers and Components" activity for North and Latin America.
The LYDYA(TM) laser diode drivers feature all the functionalities required to safely operate laser diodes and optimize their lifetime.
Laser diodes are very sensitive to:
o ESD (Electrostatic Discharges), which may cause latent catastrophic damage usually due to the breakdown of the P-N junction in an area of the device outside the optical cavity. Defects in the active region of the junction from ESD may propagate with time into the laser cavity decreasing performance and lifetime of the laser, and may appear immediately or long after the damage occurs.
LYDYA(TM) comes with an exclusive protection device: the "LYDYA(TM) diode shunt" that remains plugged to the diodes terminals and automatically short-circuits when the diode is not used.
o Reverse currents, and transients, which may destroy the diode or damage it, sometimes with no change in the current vs. voltage characteristic. Forward or reverse transients may be caused by energy reflections in pulsed systems, or output capacitors in standard constant current supplies.
LYDYA(TM)'s output stage has been specifically designed to avoid transients and LYDYA(TM) diodes shunt embeds specific circuitry - controlled by LYDYA(TM) - to get rid of transients and reverse currents.
o Excessive forward currents, which cause operation at optical power levels damaging the output facet in less than 1ìsec.
LYDYA(TM)'s high power circuitry supplies an accurately regulated adjustable current and features over-current protection functionalities.
o High temperatures and sharp changes in temperature, which damage the facets and the structure of the crystal by creating dislocations which migrate to the junction, thus reducing drastically but not obviously the diode lifetime.
LYDYA(TM) features a programmable slow-start ramp of current, as well as temperature protection interlocks. An optional temperature controller with a ramp in temperature can also be embedded into LYDYA(TM). This device protects your diodes against peaks in temperature and allows you to use your diodes safely.
The LYDYA(TM) Q-CW and CW laser diode drivers are for single diodes, bars and stacks, and range from a few watts up to several kilowatts with or without TE temperature controller. They are fully computer controllable and are capable of managing a complete laser system in a single device (cooling system, user safety management, Q-switch triggering, optical power measurement...). It is also possible to get a customized complete fiber-coupled diode laser from LASELEC since the company complements its range of LYDYA(TM) products with a laser diodes integration service.
All in all, LYDYA(TM) is the perfect driver for lab experiments, as well as for OEM integrators, to save on expensive hardware and software development, and to fulfill time-to-market targets.
LASELEC will be available to meet with you at the PHOTONICS WEST conference to be held in San Jose, California (USA) from January 22 to 27, 2005; at the CLEO conference in Baltimore, Maryland (USA) from May 24 to 26, 2005; and at the LASER conference and exposition in Munich (Germany) from June 13 to 16, 2005.
