Where to Buy Laser Diode Drivers

Alpes Lasers offers QCL laser drivers for pulsed and continuous-wave operation. Pulse widths as low as 20 ns are achievable with repetition rates up to 1 MHz.

Artifex Engineering's LDD100 is a fast pulsed current source for driving laser diodes and high power LEDs. We offer this instrument with various end stages with current ranges from 1 A to 600 A. The graphical user interface is clear and intuitive to use. These drivers are ideal for testing laser diodes.

APIC produces a turnkey tabletop laser drive module specifically designed to operate its high power, ultra low RIN lasers. The OEM laser of choice is integrated into the laser drive module at the factory. The laser drive module includes a high-quality laser driver with a low-noise power source, current driver and accurate temperature control circuit to maintain stable laser output with minimal noise. APIC is in the process of developing a similar turnkey driver module for its Direct Modulated Lasers (DML).

A high-quality laser driver with a low-noise power source, current driver and accurate temperature controls is required. If you do not have such equipment, we recommend you consider purchasing our turnkey tabletop CW laser drive module. The drive module has power conditioning with laser and TEC control electronics designed specifically to operate our lasers with minimal noise.

EKSMA Optics offers the uniLDD universal laser diode drivers. uniLDD is a DC input power converter designed to supply CW or pulsed current for single emiter, bar or stacked laser diodes in constant current (CC) mode. Drivers can be supplied for a wide current range as well as for a wide diode compliance voltage range.

Apart from a well-engineered optomechanical design and the integrated laser diode, the most important part of a tunable diode laser system is its driving electronics, which is responsible for getting the most out of a laser system.

Wide mode-hop-free tuning with Littrow setups requires a well-defined interplay between piezo actuator and current driver. Drifts of the laser diode current, the temperature or the piezo voltage determine the drift of the laser frequency and the stability against mode-hopping. Noise on any of these outputs increases the laser linewidth. The digital DLC pro represents the latest stage of development of laser control electronics. Its noise and drift properties are even better than the well established and widely used preceeding electronics SYS DC 110.

The ultra-low-noise D2-105 laser controller offers the lowest current noise of any laser controller on the market. It also features 10 MHz bandwidth of frequency control and two stages of temperature control.

The economical SLICE-DCC Dual-Channel Current Controller offers two low-noise current sources with an intuitive user interface.

Aerodiode offers a wide range of laser diode drivers as OEM devices for use by laser manufacturers or R & D teams. Some models are suitable for driving high-power diode bars or diode stacks, while others can generate nanosecond pulses for both laser diodes or SOAs. All of them have an integrated TEC controller for thermal management. Ultra-low-noise models are also available.
