The use of laser technology in micromachining has become increasingly popular due to the wide range of advantages it offers. It allows for precise control over the size, shape, and depth of the machining process, as well as providing higher accuracy and repeatability than traditional machining methods. Laser micromachining repairs provide a fast turnaround time as the repairs can be completed in a matter of hours instead of days.

To understand the different laser technologies used in micromachining, it is important to first understand the basic principles of laser operation. Laser light is created when electrons in a particular material are excited and then released in a specific direction.
The most common laser technologies used in micromachining are CO2 lasers, diode lasers, and fiber lasers. CO2 lasers are used for cutting and engraving, as they provide greater power and accuracy than other laser types. Diode lasers are ideal for welding, as their low power allows for welding at high speeds and with minimal heat. Fiber lasers are especially suited for marking and engraving, as they generate a focused beam of light that is more powerful.
In addition to the laser technologies mentioned above, there are also other advanced laser technologies available for micromachining. These include laser ablation, which uses a focused laser beam to remove material from the surface of the workpiece. Laser etching is also used for the creation of intricate patterns and designs on a variety of materials.
