Bare Chip Laser Singe Emitters and Bars

Description

A bare laser diode chip or bar is a semiconductor laser that either has a single emitting point or an array of stripe emitters in a single chip operation in continuous wave (CW) or quasi-continuous wave (QCW) with wavelength options  760/792/808/905/915/940/976/1020/1060nm and with powers from watts to hundreds of watts.

Bare chip laser single emitters and bars are semiconductor laser devices that consist of a single laser diode chip or multiple laser diode chips arranged in a linear or stacked configuration. These devices are commonly used in applications such as telecommunications, sensing, spectroscopy, and laser printing.

The fabrication process for bare chip laser single emitters and bars is similar to that of other laser diode 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 emitters.

Bare chip laser single emitters and bars can provide high-power and high-brightness output, as well as improved beam quality and spectral purity compared to some other laser technologies. They can also be designed for use in both continuous wave and pulsed operation modes.

In telecommunications applications, bare chip laser single emitters and bars are used as optical sources in fiber optic communication systems. They provide high-speed data transmission over long distances with low signal loss and high reliability.

In sensing and spectroscopy applications, bare chip laser single emitters and bars are used for their narrow spectral linewidth, which enables high resolution and accuracy in measuring physical and chemical properties of materials.

In laser printing applications, bare chip laser bars are used to expose and modulate the photoconductive properties of a printing plate, enabling high-speed and high-resolution printing.
