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!

Output Current LD 0.5 A; Chassis Mount; Compatible with Type A & B Lasers  Wavelength Electronics’ FL591FL series of laser diode driver evaluation boards allows you to quickly and efficiently evaluate Wavelength Electronics’ FL500 laser diode driver and prototype your laser electronics system. The evaluation board is designed so that you can fully characterize the included FL500 — you’ll know exactly how it will perform in your application, and there will be no surprises during the development process. Ultimately, you’ll bring your system to market faster and at lower cost. FL591FL can be configured to drive a single 500 mA output or two 250 mA independent outputs by setting onboard jumpers. The drivers operate in constant current or constant power modes. Onboard current setpoint and limit trimpots mean no external electronics are required to operate the drivers. Simply connect the power supply and laser diodes, and you’re ready to go. The FL591FL series is loaded with useful features to help simplify the prototyping process. For example, there are several setpoint-output combinations: Two independent outputs, each driving up to 250 mA, and controlled by separate setpoint signals or by a single setpoint signal alternatively; two independent 250 mA outputs controlled by a single setpoint signal; a single output, driving up to 500 mA. The current limits are set using onboard trimpots and without enabling the output. The setpoint is controlled using the onboard trimpots or the BNC connector for external control – or the two can be summed. Summing the setpoint signals makes modulating a laser easy and foolproof. The control mode — constant current or constant power — is set with onboard switches. When operated as two independent drivers, the two channels can be operated in different modes. An external signal is required to enable the output; this Enable input can be connected to a safety interlock or coupled to a temperature controller that will disable the output if the lasers exceed a safe operating temperature. Drive current and photodiode current monitor outputs can be tied to an external control and monitor circuit so you can characterize every aspect of your laser control system. The FL991FL series provides easy access to the setpoint and current limit reference signals for design evaluation and validation of your laser control electronics. It is also available without the FL500 controller installed – please contact AMS Technologies.

Output Current LD 200-400 mA; DIP PCB Mount; Compatible with Type A, B & C Lasers  Wavelength Electronics’ LDD P series of laser diode drivers come in two compact models to work with all laser diode/photodiode configurations. While the LDDX00-1P version drives type A & B laser diodes, the LDDX00-2P variant drives type C laser diodes. Each model is available in 200 mA and 400 mA versions to best fit your laser diode requirements. Very low leakage current (15 µA) makes the LDD P series ideal for driving most VCSELs using the remote modulation setpoint input. It operates from 5 to 12 V. Just add an external power supply and your laser diode to this simple 8-pin controller. When it is essential to have high performance in your application, these low-noise drivers offer excellent current stability in constant current mode. Precisely control the laser diode setpoint current with the onboard output current adjust trimpot or via a remote voltage to the modulation input. The modulation input’s small signal 3 dB bandwidth is DC to 2 MHz. For easy integration, the LDD P series allows users to measure laser diode current from a buffered monitor output. Optional evaluation boards are available to assist with operating any LDD P series module. An evaluation board and cable are available to speed implementation of the LDD laser diode driver in your application. In order to protect laser diodes, all LDD P series drivers are equipped with current limit protection, as well as slow start circuitry. Current limit protection ensures that the diode will not be overdriven, and the slow start circuitry protects the diode from thermal shock that can damage the laser at turn on. Adjust the limit current trimpot to protect the laser diode from exceeding its maximum current rating even when modulating your laser diode.
