Design flexibility from the component to the sub-system level

Leveraging our proprietary heat sink & assembly technology in order to provide mounted diode lasers with industry leading performance

Three figures of merit - optical output power - electro-optical (EO) efficiency – and package lifetime - characterize the performance of diode lasers operating at a desired emission wavelength and operating mode.

The most critical part in diode laser selection is not optical output power but optical output power at a well-defined reliability point required by the application.
Whether you focus on maximizing optical power at the expense of lifetime or maximizing lifetime at de-rated optical power conditions - we will support you in making the right product selection.

We at Jenoptik have pioneered high-power diode laser assembly in high-volume manufacturing and have been one of the first companies to introduce AuSn-soldering in the field.

While still applying industry standard heat sink designs (CS, CT) and established assembly technologies based on In- or AuSn-soldering, we at Jenoptik are mainly focusing on 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 exchange between our in-house fab and our laser assembly site allow to tailor the laser bars employed towards the specific heat sink technology and the desired operating mode to be applied.

Optional beam collimation using microlenses or optional beam shaping using diffractive optical elements (DOE) round up our open heat sink laser technology portfolio in order to match your optical interface.

Featuring up to 300 W optical output power with our latest open heat sink generation LK

Benefit from our industry leading open heat sink diode laser product technology LK to translate increased power per mounted laser bar into reduced complexity and thus reduced cost of ownership on the system level – may your application be in optical pumping or DDL technology.

Optical output power levels up to 300 W in cw- and even hard-pulse mode can be reached in the 9xx nm region by combining Jenoptik's state-of-the art laser bars with our latest innovation in die-mounting and assembly technology.

Power scaling into the multikilowatt range for cw- and qcw-operation

Vertical stacking of individuals sub-mounts within multi-laser-bar packages offers a highly modular approach for power scaling well into the kW-range.

The modularity inherent in high-power diode laser arrays allows to flexibly scale-up a laser stack to the requested power level at a given center wavelength.

Vertical stacks are the diode laser package of choice for applications requiring primarily highest power levels.

Beam quality (beam-parameter-product, BPP) is optimized to the extent possible by applying lowest pitches (= distance between neighboring stacks) approaching 1,0 mm without compromising on cooling capacity of the submounts.

All our vertical stacks are tried & tested under application-specific conditions ranging from medical, industrial to mission-critical end use. Our proven hard-solder technology covers even the harshest environmental conditions.

Given the high modularity inherent in diode laser stack technology there is no one fits all solution.

Our trusted 532 nm laser sources with up to 8W continuous-wave output power for proven applications in medicine, illumination and signaling

Jenoptik has pioneered development and commercialization of diode-pumped thin disk laser technology and has over 30 years experience in the design and fabrication of diode-pumped solid state lasers.

With more than 25.000 units installed, our cw-532 nm thin disk lasers are proven in the field for a variety of applications such as ophthalmology, dermatology, veterinary medicine, laser projection and quality control.

Operation of our 532 nm thin disk lasers relies on TEC-controlled laser diode pump sources from our in house-fab, Nd:YVO4 gain crystals and TEC-controlled internal frequency doubling LBO crystals.

Compared to other solid-state laser technologies, thin disk lasers offer highest electro-optical efficiency, water-less cooling of the gain medium and high beam quality (M² ~ 5) due to suppression of thermal lensing. This enables us to serve applications in the medical field of laser-based-therapy with our proven and highly reliable JenLas® D2.x and JenLas® D2.mini series.

The miniaturized JenLas® D2.mini 2-8W with its industry-leading, lowest form-factor fits into the palm of your hand and exhibits a rugged, sealed OEM-design for easy integration into your medical laser system.
