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

Driving new high power diode-laser based applications in optical pumping and DDL-technology.

Open heat sink LK in fingers

Jenoptik´s latest mounting and assembly technology for high power open heat sink diode lasers presents the new standard for ambititous customers seeking to expand applications in optical pumping or direct-diode laser technology.

The LK heat sink serves as the building block for novel low- or high-brightness applications, e.g. based on spatial and spectral beam combining techniques.

Optical output power levels up to 300 W in cw- and even hard-pulse mode can be reached in the 9xx nm region.

High Performance - thanks to technology

Thanks to our latest innovations in mounting and assembly technology, our new high power open heat sink diode laser generation LK can achieve optical output power levels far exceeding those of e.g. the industry standard CS.

Established die-mounting technologies rely on laser bars being soldered with indium- or gold-tin solder. Especially under hard-pulse conditions, i.e. periodic operation of the diode laser between below-threshhold- and operating current at sub-second intervals, soldered connections are prone to mechanical failure. Jenoptik has therefore developed a new, solder-free technique which results in a more robust, hard-pulse-stable connection, which can withstand the temperature fluctuations arising during hard pulse operation.

The design of the LK heat sink exhibits double-sided cooling and additional heat sinking capacity thanks to its protruding nose, and thus ensures optimum heat sinking capability resulting in thermal resistance values as low as < 0,25 K/W for high power laser bars up to 300 W (cw, hard-pulse).

Simplified power scaling and system assembly resulting from higher ouput power per package, present a major value add for our customers.

Stay ahead of the market and develop your next high-power diode laser system with Jenoptik's latest generation in open heat sink technology.
