Fast rise time to high currents in a load such as a laser diode array is achieved by connecting an inductor between a power supply and an end of the diode array.
High power pulsed laser diode driver.
These ultra high power laser diode drivers from quantel offer up to 500 amps of output current and up to 100 volts of compliance voltage.
These are by no means standards just a generalization based on the author s experience in the laser diode controller world.
With output currents to 200amps the lddhc series high power laser diode driver is available in 3 power levels and a wide range of compliance voltages.
What is a pulsed laser diode driver.
Ideal for r d or manufacturing testing precision low noise current control with set point accuracy of 0 1 of reading is delivered to the lasers with four wire voltage measurement and a photodiode monitor with adjustable reverse bias for cw and qcw liv testing laser.
A high power laser diode driver is 5 amps and up to 100 s of amps in a cw mode.
Ldx 36018 35 laser diode driver high power cw qcw 18a 35v gpib.
When the shunt switch is opened energy stored in the inductor is suddenly delivered to the.
Each ldx 36000 series laser diode driver was designed as a current source specifically for high power laser diodes.
They can be configured for multiple high power current and voltage ranges.
A shunt switch is connected across the diode array.
