Distributed Feedback (DFB)

Distributed Feedback (DFB) Lasers Overview

Distributed Feedback (DFB) Laser Diodes are single frequency and offer a Narrow Linewidth with good side mode suppression. A Bragg grating is utilized to ensure single frequency emission.

Discreet-Mode (DM) Laser Diodes offer very similar performance to DFB Lasers. Discreet-Mode (DM) Laser Diodes are produced with a simple and low-cost fabrication process and have many advantages, such as very high side mode suppression ratio, stable operation over a broad temperature range, narrow linewidth and low sensitivity to optical feedback.

Free space and fiber pigtailed versions are available in these IR narrow linewidth lasers.

We offer a wide range of wavelengths and output powers to choose from in our DFB Lasers.  Contact RPMC for a quote or more information.

EP Series

EP2108-DM-B: 2108nm DM Laser Diode 1950-2150nm

The EP series is a tunable single-frequency diode laser available in wavelengths from 1270nm thru 2300nm. Utilizing Eblana’s proprietary discrete-mode (DM) technology ensures excellent side mode suppression ratio (SMSR), without the mode hops inherent to most distributed feedback (DFB) lasers.

QCL Series

mirSense Product Family

The QCL series is a high power pulsed Quantum Cascade Laser based on proprietary technology which incorporates high-powered diodes (typically watt-level) emitting in the main transmission bands of the atmosphere (4.0µm, 4.6µm, 4.8µm, 9.x µm). The ITAR free MirSense technology exhibits outstanding performance in terms of power and wall-plug efficiency. This high-performance QCL laser assembly takes full advantage of MirSense’s state of the art technologies.
