Laser Diode Horizontal Stacks

Description

Laser diode horizontal stacks are used for the tasks that require side-pumping and can consist of several bars. Models with center wavelength 808/915/940/980/1064nm are available.

Laser diode horizontal stacks are high-power semiconductor laser devices that consist of multiple laser diode bars integrated into a single package, oriented in a horizontal configuration. These devices are commonly used in materials processing, medical equipment, printing, and imaging applications where high output power and beam quality are required.

Each laser diode bar in a horizontal stack typically contains several individual laser diodes, and the total output power of the device can range from a few watts to hundreds of watts, depending on the number of laser diode bars and the design of the device.

The fabrication process for laser diode horizontal stacks is similar to that of laser diode bar chips and modules. It 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.

The orientation of the laser diodes in a horizontal stack allows for efficient cooling of the device, as the heat generated by the high power output can be dissipated through a larger surface area. In addition, the horizontal configuration enables easy coupling of the output light into an optical fiber or other delivery system.

Laser diode horizontal stacks 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.
