Distance measurements are often done with modulated low-power diode lasers. Similar lasers are used in laser printers, scanners and bar code readers.
Broad area laser diodes, diode bars and diode stacks are often used for diode pumping of solid-state lasers. Fiber-coupled broad area LDs also serve as pump sources of fiber amplifiers.
Some kinds of surgery (e.g. treatment of enlarged prostates) and dermatological therapies can be done with radiation from diode bars.
High-power diode stacks are directly used in laser material processing in cases where a high beam quality is not required, e.g. for surface hardening, welding and soldering. Compared with other high-power lasers, they are simpler and have a much better wall-plug efficiency.

Laser Diode Astigmatism:

As laser diodes have evolved over the past fifteen years, various structures have been developed with different characteristics.
The first laser diodes used gain-guided structures, which are easy to fabricate, resulting in a reliable device at low manufacturing costs.
This type of structure supports multiple modes, resulting in multiple spectral lines and astigmatism. Astigmatism is a condition in which the apparent focal points of the two axes do not coincide.
It limits the ability to focus the laser beam to a small spot size and complicates focusing the output beam to a sharp well-defined point.
