ALPHALAS
FIBER-COUPLED LASER DIODE
WITH DRIVER & TEC CONTROLLER
LDF-30
Fiber-coupled laser diodes with output power up-to 30 W integrated in our laser
drivers provide a compact and efficient air-cooled solution for solid-state laser
pumping, material processing and scientific applications. The drivers have all
protective features for reliable and safe operation, including soft start, true currentsource operation, overtemperature and undertemperature limits, current limits,
temperature sensor fault alarm, laser diode loop check, etc.
Due to newest electronic design and production technology ALPHALAS provides
the most compact solution for a ready-to-use fiber-coupled laser diode worldwide,
combined with the most universal laser diode driver. The option with built-in
frequency generator expands the capabilities for pulsed mode of operation. Thus,
the laser diode can be operated in CW, pulsed, or combined CW/pulsed mode
(biasing). The back-lighted liquid-crystal display monitors numerous important
parameters as laser diode current, TEC module current and current limit, measured
and set LD temperature, and temperature limit.
Higher output powers from fiber-coupled laser diodes are also available, as well as
custom designs.
