The main advantages of laser drilling, they include:

No Drilling Vibration - Since laser drilling is a non-contact process, it does not cause any drilling vibrations. There is also no damage to the material.

Accuracy - The biggest advantage of laser drilling is the ability to control beam intensity, heat output, and the duration of the laser beam. This means that the precision and accuracy of the hole, is a given!

High Aspect Ratio - With laser drilling, high aspect ratios can be provided. A typical microwell is known to have an aspect ratio of 0.75:1.

Multitasking - Laser machines can also be used for processes such as welding and cutting.

Different types of laser drilling

There are many types of laser drilling, the following are:

Single pulse/laser drilling

This drilling is one in which both the laser source and the working material remain stationary and emit a single laser beam.

Percussion Laser Drilling

In this method, a series of laser pulses are fired. It works well for creating deeper and smaller holes.

hole

During this process, the laser beam is guided around a predetermined trajectory. It is especially useful when the diameter of the desired through hole is larger than the diameter of the laser beam.

Helical Laser Drilling

In this method, the laser beam follows a helical path while rotating around its own axis. While laser drilling has many of the advantages detailed earlier, there are some caveats to keep in mind when using it.
