Laser Diode Bar Chips

Description

Laser diode bar chips are bare dice that have several laser chips combined in one bar to join the power of single laser to produce units of dozens and even hundreds watts. Main application for laser diode bar chips is medical, laser machining, free space optical communication.

Laser Diode Bar Chips are high-power semiconductor laser devices consisting of an array of individual laser diodes that are fabricated on a single chip. Laser diode bar chips are used in a wide range of applications, including materials processing, medical equipment, printing, and imaging.

Each individual laser diode in a laser diode bar chip is designed to emit light in a narrow spectral range, typically in the near-infrared region. The output power of each laser diode can range from a few hundred milliwatts to several watts, depending on the design and size of the device.

Laser diode bar chips can be designed to emit light in a continuous wave (CW) mode or in a pulsed mode. In CW mode, the laser diodes emit a continuous stream of light, while in pulsed mode, the laser diodes emit short bursts of high-intensity light.

The fabrication process for laser diode bar chips typically involves epitaxial growth of the active and cladding layers on a substrate, followed by lithography and etching to define the device structure. The individual laser diodes are then formed by cleaving or dicing the device into smaller pieces, each containing one or more laser diodes.

Laser diode bar chips are often packaged with additional optics and electronics to enable efficient coupling of the light into an optical fiber or other delivery system. The packaging also provides thermal management to dissipate the heat generated by the high power output of the device.

Overall, laser diode bar chips provide high-power and high-brightness output that make them suitable for a range of industrial and scientific applications.
