Laser Diodes. Redefined.

Eblana Photonics' core product offerings are based on our patented Discrete-Mode (DFB like) manufacturing technology, which delivers industry leading performance with fully scalable, consistent production and integration capability.

Eblana’s products are used extensively for trace gas sensing and environmental monitoring in the near- and mid-IR.

In addition, the inherent low linewidth performance of the DM platform in comparison to typical DFB lasers is uniquely suited to distributed fibre sensing and LIDAR applications, as well as scientific and metrology projects.

SHIPS TODAY: AeroDIODE offers fiber-coupled laser diodes between 520 nm and 1650 nm as stock items or associated with a CW or pulsed laser diode driver. They are compatible with our high speed nanosecond pulsed drivers or high power CW drivers (with air cooling) for the multimode high power laser diode versions. The single mode laser diodes (either Fabry–Pérot laser diode or DFB laser diode) can reach high power in nanosecond pulse regime up to 400 mW. Most turn-key diode & driver solutions are optimized for single-shot to CW performances with pulse width lengths down to 1 ns. The laser diode precision pulses are generated internally by an on-board pulse generator, or on demand from an external TTL signal. Many multimode versions are available with CW emission up to 450 W in a 200-µm core multimode fiber or up to 250 W in a 135-µm core fiber or 160 W in a 105 µm core fiber.
