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.
Your OEM Laser Diode Solution Awaits!
Many configuration options available:
- Wavelength: Options from 760-1070 nm
- Optical output power: up to 300 W
- Operating mode: CW or QCW
Cooling Options:
- Passively cooled heat sinks, i.e. single-bar packages which conductively spread and transfer dissipated power to a baseplate before waste heat is ultimately removed, e.g. via tap water cooling of the baseplate
- Actively cooled heat sinks i.e. single-bar packages which are directly cooled with water in order to convectively remove the heat directly from the heat sink
- Active cooling allows for a smaller and narrower heat sink design which still make this heat sink technology an attractive building-block for densely packed horizontal arrays serving e.g. side-pumping applications
Packaging Options:
While still supplying industry standard heat sink designs (CS, CT) and established assembly technologies based on In or AuSn soldering, Jenoptik is leveraging our proprietary, cutting-edge heat sinking and die attach technologies within our double-side passively cooled packages CN, LS and LK in order to serve most advanced optical pumping schemes and direct-diode-laser (DDL) technology.
Close cooperation between our in-house laser bar fab and our laser assembly site ensures a laser bar tailored to the specific heat sink technology, operating parameters, and application specific needs.
Lensing Options:
- Beam collimation using microlenses.
- Beam shaping using diffractive optical elements (DOE).

Advanced LK Heat Sink Technology
Take advantage of our industry-leading open heat sink diode laser product technology, LK. This technology translates the increased power from each mounted laser bar into a simpler system, reducing the overall cost of ownership. This is beneficial whether your application involves optical pumping or DDL technology.
Our state-of-the-art laser bars, when combined with our latest advancements in die-mounting and assembly technology, can achieve optical output power levels of up to 300 W in both continuous wave (CW) and hard-pulse modes. This is possible in the 9XX nm region. With Jenoptik, you’re always at the cutting edge of technology.
