QCW Laser Diode Modules

Quasi-continuous wave fiber lasers are now part of the equation for modern applications. They can operate in both CW and high-peak power pulsed modes. Unlike traditional CW lasers, for QCW Fiber Lasers Come of Age Wall-plug efficiency, high PPR are just two benefits of new laser technology FABRICATING which peak and average power are always the same in CW and CW/ modulated regimes, QCW lasers’ peak power in pulsed mode is increased by a factor of 10 over the average power.

JDL Series

Unmounted Laser Diodes Unpackaged Laser Diodes - gold bars laid out on a grid in a black gel pak

The JDL series offers industry-leading custom high-power unmounted laser diode bars in the 760-1070 nm spectral region. Our unmounted laser diode bars are available in a wide range of emitter configurations, cavity lengths, and CW or QCW operational modes. We offer low fill factor bars suitable for fiber coupling, high-power bars up to 300W for CW or hard-pulse industrial DDL applications, and QCW bars up to 500W for QCW or long-pulse optical pumping and medical applications. With full customization options including custom designed epitaxial wafer structures, you’re sure to get the perfect solution for your needs.

JOLD-FC Series

The JOLD-FC series of high-power fiber-coupled laser diode arrays (bars) provide a cost-effective and robust solution for OEM applications.  With superior reliability and efficiency, our lasers offer industry-leading performance. We offer standard wavelengths of 760-1070 and 1470 nm, with 200, 400, or 600 µm fiber core diameters. Other optional components include pilot lasers, monitor diodes, and integrated Peltier elements, available in the JOLD-FC series, ensuring you get exactly what you need.

JOLD-Open Heatsinks Series

various brass or gold colored laser diode bar/array housings

The JOLD-Open Heatsinks Series offers industry-leading, reliable, and cost-effective high-power free-space single-laser-bar packages based on passively or actively cooled heat sinks in the 760-1070 nm range. Our proprietary heat sink and assembly technology, paired with our focus on advanced optical pumping and direct-diode-laser technology, results in diode lasers with unmatched performance including optical output power, electro-optical (EO) efficiency, and lifetime. This series offers options from 792 nm up to 1035 nm, and average output powers up to 300 W CW with passive cooling.

JOLD-Stacks Series

various sleek modern brass and stainless steel laser diode bar stack housings

The JOLD–Stacks Series offers a highly modular approach for power scaling well into the kW range. The series features compact, lightweight, and robust multimode, free-space laser diode stacks with options for 760-1070 nm, CW & QCW operation, output power up to 2400 W (QCW), no lensing or FAC or FAC/SAC collimation, active or passive cooling, and are completely customizable. JOLD-Stacks achieve optimal beam quality by reducing the stack pitch without compromising cooling capacity, and our proven hard-solder technology and strictly monitored production processes ensure tried & tested reliability in the harshest environments.

PowerMir Series

mirSense Product Family

The PowerMir series is a line of high-power, pulsed Quantum Cascade Lasers based on proprietary technology, available in wavelengths from 4-9 µm and either turnkey benchtop systems, OEM driver + laser module, HHL package, or chip. Our lasers operate in Quasi-Continuous Wave (QCW) mode, enhancing wall-plug efficiency and thermal dissipation. The PowerMir series is ITAR-free, featuring high-powered diodes that emit in the primary atmospheric transmission bands. Our lasers produce a circular TEM00 Gaussian beam for superior performance.
