Laser Diode Bar Array

For even higher power applications these bars can be stacked and put into a single package capable of producing kilowatts of laser power.

Laser diode bar array.

Visible ir laser diode high power bars stacked arrays individually addressable arrays quantum well intermixing technology vcsel. One of the unique features is a user programmable soft start ramp of the bias current to the device under test. Single bar mounts vertical and horizontal diode laser stacks linear arrays direct diode lasers and fiber coupled lasers. The figure below shows a typical structure of a laser diode array.

They typically contain between 20 and 50 emitters each being e g. 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. A wide variety of wavelengths are available 640 nm 1920 nm in both continous wave cw and quasi contnous wave qcw operation modes. All products laser diodes laser bars and arrays.

High power diode laser packaged bars and arrays. Customized protection for high power laser bars and arrays these current sources feature multiple levels of built in laser diode protection which have been optimized for bars and arrays. 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. Packed with our patented solder free clampingtm technology.

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. 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. 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.
