Description
The LD-1500A/3000A
are QCW high power laser diode drivers capable of 20KW (170V/120A)
output power. The QCW time period is limited by both average powers and
current droop specified. LD-1500A/3000A
are also designed as high speed, high current CW/pulse laser diode
drivers, of which CW power are 1.5KW and 3KW respectively and the
peak current is up to 350A with
the rise time of 50ns in Super Pulse mode.
LD-1500A/3000A uses
a high frequency PWM modulation to convert AC input power to a
desirable DC output voltage. The magnet components
weigh only 14OZ
(400g, LD-1500A), or 28OZ (800g, LD-3000A) due to the Lic's
unique magnet core technology and the high frequency power
conversion experience accumulated in house for over 24 years.
Optional
unit of LDC-120 is
designed to enhance the output pulse characteristics to the maximum of 800 picoseconds rise time, 1.5 ns pulse width,
& high peak pulsed output of 120A/400V (Super Pulse). This
unit contains a precise( 40ppm/C), 15MHz internal PWM-pulse generator.
