Ratings shown indicate upper operating limits. Electrical output refers to power delivered to the laser diode, not optical power. See each model’s specifications for operating conditions, input supply and cooling requirements. LDD enclosure: 74 × 63 × 26 mm; TKLM-DT enclosure: approximately 165 × 160 × 51 mm. LDD images illustrate the series enclosure. * TKLM-DT laser output voltage depends on the selected configuration.
Need a laser diode driver outside our standard LDD range? ePhotonics develops custom high-power laser drivers for OEM, industrial, and scientific systems. We can adapt the current range, compliance voltage, form factor, modulation, protection, thermal management, and control interface to your application.
Start with your laser diode's operating current and forward voltage. Match those requirements to the driver's current range and compliance voltage, then check modulation timing, control interfaces, power-supply requirements and cooling. If your system also needs active diode temperature regulation, consider a laser diode driver with TEC control.
The LDD series includes models with maximum current ratings of 10 A or 16 A and maximum compliance voltage ratings of 30 V, 60 V or 100 V, depending on the model. These are maximum ratings; see each model's specifications for its current adjustment range. LDD1630 and LDD1660 are coming soon. The TKLM-DT has separate, configuration-dependent specifications.
Compliance voltage is the maximum output voltage available while the driver regulates current. It must cover the diode's forward voltage and wiring losses. Check input-supply requirements separately. Our laser diode driver compliance voltage calculator helps estimate the voltage needed by your diode and cables.
Continuous-wave (CW) operation drives the laser diode continuously. Pulsed operation controls the drive current over defined time intervals. The LDD series supports CW and pulsed operation. For pulse applications, check the selected model's rise and fall times, supported pulse widths, repetition rate and duty-cycle limits against your requirements.
Constant-current (CC) control regulates the current through the laser diode. Constant-power (CP) control adjusts that current using optical feedback, such as a compatible monitor photodiode signal. CP operation requires a suitable feedback arrangement. Confirm the supported control modes and feedback connections for your selected driver.
Yes. The TKLM-DT laser diode driver with TEC controller combines laser current control with thermoelectric temperature control. Configurations support up to 16 A laser current, up to 24 V laser output and up to ±15 A TEC current. Maximum laser output voltage depends on the selected configuration. Pricing and lead time are confirmed with a quotation.
The LDD series measures 74 × 63 × 26 mm and is designed for OEM integration. The TKLM-DT measures approximately 165 × 160 × 51 mm and includes TEC control. Allow for connector access, mounting and the cooling arrangements required by your selected model.
Protection features depend on the model. For example, the LDD1060 laser diode driver includes an adjustable current limit and reverse-current protection. The TKLM-DT offers soft start, reverse-polarity and transient protection, and a remote interlock. Follow the selected model's documentation for protection behavior and connection requirements.
The wattage listed for the LDD series describes electrical output delivered to the laser diode. Laser optical output depends on the diode's characteristics, efficiency and operating conditions. Driver conversion efficiency describes the relationship between its electrical input and output power. Use the individual driver and diode specifications when calculating electrical load, optical output and heat dissipation.
Use a DC supply that meets the selected driver's input-voltage and input-current requirements at your intended output load. Provide cooling for both the driver and the laser diode according to their operating conditions. Check the model documentation for supply, wiring and thermal requirements.
Yes. ephotonics offers custom laser diode driver design for application-specific current, voltage, mechanical and control-interface requirements. Share your diode specifications, operating mode, integration constraints and required quantity so we can assess a suitable solution.
