Where to Buy Laser Diode Drivers

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 emitter, 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.

A large range of diode laser drivers covering CW and pulsed currents from 100 mA to 300 A are available as standard or as customer-specific products at competitive prices. The diode laser drivers are complemented with TEC drivers of various powers for easy integration into the customer’s laser systems. The product line includes also drivers for picosecond pulse diode lasers with repetition rates up to 100 MHz and laser diode current modulation up to 1 GHz.

Sacher Lasertechnik offers different types of low-noise laser controllers, including benchtop and OEM versions with digital control interfaces.

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.

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.

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.

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.
