Product information "FL500 Laser Diode Drivers"

Output Current LD 0.5 A; PCB Mount; Compatible with Type A & B Lasers

Wavelength Electronics’ FL500 series of component type surface mount laser diode drivers is ideal for driving low power laser diodes where low noise is critical. Low leakage current (150 µA) makes it ideal for driving most VCSELs. The FL500 series laser diode drivers operate from 3 to 12 V, so they are compatible with Li+ battery operation. FL500 drivers can be configured as two totally independent 250 mA drivers or a single 500 mA driver and are compatible with Type A or B laser diodes. Because of their small size and low noise, the series is often used in handheld devices and spectroscopy systems.

The base unit operates in constant current (CC) mode. The only external components required are a power supply, an analog control voltage, your laser and optional filtering circuitry. For additional features, including current limit and photodiode feedback for constant power operation, use the FL591FL evaluation board with controller.

Free, effective and responsive technical support is available to simplify integration of Wavelength products into your OEM design. Standard products can be easily modified to meet your application requirements. Get in touch with the AMS Technologies laser diode driver experts to discuss your customized solution!

1,5A QCL Driver - QCL1500

The QCL OEM Series drivers use patented1 circuitry to produce the lowest current noise density of any commercially available QCL driver. The 500 mA QCL driver exhibits noise performance of 0.5 µA RMS to 100 kHz, and average current noise density of 1 nA / √Hz - the lowest available. In order to maintain their characteristically tight center linewidths and minimize jitter, quantum cascade lasers must be powered by drivers with exceptionally low current noise density. Our customers have reported achieving narrower linewidths with these drivers than any other they've used.Key Features Off-the-shelf models at 500 mA, 1 A, 1.5 A, 2 A Can be delivered in other current ranges up to 2 A Compliance voltage 16 V (standard), Compliance 7-20 V with factory modification Safety features protect your QCL investment Adjustable soft-clamping current limit Brown-out, reverse-voltage, & over-voltage protection Driver over-temperature protection circuit Relay shorts output when current is disabled Local and Remote Power-On and Enable control,TTL-compatible Analog modulation input between -5V and +5V.
