The figure below shows a typical structure of a laser diode array.
Laser diode bar array.
One of the unique features is a user programmable soft start ramp of the bias current to the device under test.
Packed with our patented solder free clampingtm technology.
For even higher power applications these bars can be stacked and put into a single package capable of producing kilowatts of laser power.

All products laser diodes laser bars and arrays.
High power diode laser packaged bars and arrays.
Laser diodes bars and multimode laser diode stacks are available in unmounted laser diode bars or mounted in conductively or actively cooled packages.
Proudly offers diode laser packaged bars vertical arrays stacked laser diode arrays and horizontal arrays linear laser diode arrays at wavelengths ranging from 808nm to 1100nm with high output power up to 6000w in cw and qcw operation mode and different package.
A wide variety of wavelengths are available 640 nm 1920 nm in both continous wave cw and quasi contnous wave qcw operation modes.
Diode bars are high power semiconductor lasers laser diodes containing a one dimensional array of broad area emitters or alternatively of subarrays containing 10 20 narrow stripes.
In this case m icrochannel cooling is often used in laser diode bar stacks due to a large amount of waste heat in a small area.
In a bar the individual emitting areas emitters lie side by side and together with the non emitting areas between the emitters they form the so called active layer.
They typically contain between 20 and 50 emitters each being e g.
High power diode laser arrays 135 laser bars as well as single emitters are assembled with the p n junc tion very close 2 mm to the heat sink or heat spreader p side down solder and heat sink material must be chosen carefully to avoid any.
Single bar mounts vertical and horizontal diode laser stacks linear arrays direct diode lasers and fiber coupled lasers.
