Where to Buy Laser Diode Drivers

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

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.

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.

RPMC Lasers offers a wide range of laser diode drivers for CW, QCW, and pulsed operation. We offer turnkey laboratory laser drivers, rack-mountable laser drivers, and board level OEM drivers with currents ranging from 100 mA to 300 A. Additionally, the pulsed driver boards are capable of producing transform limited pluses down to 250 ps.
