Frequently Asked Questions

What current and voltage range do your laser diode drivers support?
Our laser diode drivers support output currents from 10A to 16A with compliance voltages ranging from 30V to 100V, covering a wide range of high-power diode bars, stacks, and single emitters.
Are your laser diode drivers suitable for OEM integration?
Yes, our drivers are designed with OEM integration in mind, offering compact form factors, analog and digital control interfaces, and robust protection features suitable for embedding in industrial and scientific systems.
What protection features are included in your laser diode drivers?
Our laser diode drivers include built-in protection against overcurrent and reverse polarity to safeguard both the driver and the connected laser diode.
What is the size of your laser diode drivers?
Our laser diode drivers feature an ultra-compact form factor of just 57 x 60 x 22 mm, making them ideal for space-constrained OEM and embedded system designs.
What is the difference between CW and pulsed laser diode drivers?
CW (continuous wave) drivers supply a constant current to the laser diode, making them ideal for steady-output applications like pumping or illumination. Pulsed drivers modulate current in short bursts, enabling high peak power for applications such as LiDAR, range-finding, and material processing. All of our drivers can be used in CW or pulsed mode.
What is the power efficiency of your laser diode drivers?
Our laser diode drivers achieve a power efficiency of more than 94%, minimizing heat dissipation and reducing thermal management requirements in your system.
What is the long-term current stability of your laser diode drivers?
Our laser diode drivers deliver outstanding long-term current stability of 250 ppm, ensuring consistent laser output over extended operating periods.
How much do your laser diode drivers weigh?
Our laser diode drivers weigh only 140 grams, making them one of the lightest high-power drivers available for portable and weight-sensitive applications.
Do you offer custom laser diode driver design services?
Yes, ephotonics offers custom laser diode driver design services tailored to your specific voltage, current, size, and interface requirements. Learn more on our Custom Laser Diode Drivers page.
