3 Amp Pulse Driver For Laser Diodes, ILX Model LDP-3840B

ILX Model LDP-3840B Pulsed Driver

The LDP-3840 series drivers are simple to set-up and operate. They have all of the adjustments that you need to access on the front panel, and you can see your settings on the front panel. They are also one of the only pulsers on the market that have a GPIB interface. They are somewhat limited because they can't offer pulses less than 100 nanoseconds. Also, you need to use an external mounting board to match the impedance of our laser diode with the output of the driver. But impedance matching is a concern with any driver.

These pulse mode drivers are designed for laser diode applications which require > 100 nanosecond pulse widths. These units offer an intuitive front panel and they deliver pulses with amplitude of 0 to 3,000 mA. They offer rise and fall times less than fifty nanoseconds with low overshoot. They are specified to provide less than five percent overshoot on a 100 nanosecond pulse. The key parameters such as pulse width, duty cycle, and frequency are all programmable using LabVIEW drivers and and GPIB interface. These units offer 2 modes of operation. They can be run in constant duty cycle and constant frequency allowing adjustment of the pulse width while maintaining either respective control mode. Testing and characterization. A trigger signal can be used to generate the pulses to the laser and to initiate the corresponding measurements. An analog output proportional to the current set point is available through a BNC connector on the rear panel.
