Fiber Laser Applications: Laser Drilling

Fiber lasers are incredibly versatile and capable of many different fiber laser applications, ranging from precision micro-machining operations, to heavy duty industrial processes i.e welding.

This month, our focus will turn to Laser Drilling, a precision application which is highly beneficial to manufacturing companies.

In this article, we will discuss what laser drilling is, how and where it is used, and what advantages the application has to industry.

Fiber Laser Drilling: An Introduction

Laser drilling is a precision application for creating holes in a variety of materials, such as metals, plastics, and ceramics.

Fiber Lasers are particularly effective for drilling holes in a variety of metals, as they allow the user to adjust the beam creating holes from just a few microns wide.  That said they can also be used to process other materials such as plastics and ceramics.

For instance, lasers are often used to drill micro-holes in semi-conductors made from silicon, which are found within many household components such as televisions and washing machines.

Fiber Lasers are used by the medical, automotive, aerospace, and electronics sectors for drilling, due to their versatility, speed and cost effectiveness.

Fiber Laser applications such as drilling are important to the electronics industry

Drilling holes between the different layers of the semi-conductor helps with the flow of electrical current.

How it Works

Laser drilling is achieved by modulating pulses in order to melt the material layer by layer. Different materials require different pulse parameters.

There are various types of laser drilling, which operate in different manners. These include Single-shot laser drilling, Percussion laser drilling, Trepan laser drilling, and Helical laser drilling.

To understand the differences between them, visit our Apps Insight entitled, “Laser Drilling | The Various Types, Techniques & Processes of Laser Drilling“.

Our flexible redENERGY Pulsed fiber lasers feature PulseTune technology – allowing you to fine-tune ‘pulse waveforms’ for greater depth of quality and control.

Our redPOWER CW fiber lasers are also suitable for laser drilling, as they offer integral pulse shaping for adjusting peak power and pulse energy.

Ultimately, you can achieve this application using either of our pulsed or CW lasers.

What are the advantages?

To help new users understand why fiber laser technology is the best drilling solution for manufacturing companies, we have compiled a list of benefits for you here:

1) Ultimate precision

Laser drilling offers greater accuracy and control, meaning that it can be used to drill holes in a variety of shapes and sizes.

2) Repeatability/Consistency

Single-shot laser drilling will enable you to drill multiple holes quickly, which you can repeat again and again until you reach the required quantity.

3) High-speed applications

Fiber lasers deliver higher power and pulse energy than alternative laser technology meaning they are also quicker.

4) Zero-maintenance

Fiber Laser Drilling is crucially a non contact process, providing a maintenance-free drilling solution for your industrial manufacturing challenges, as opposed to existing technologies; this often also results in significant cost savings due to reduced down time and parts replacment costs.

5) Flexibility

We offer versatile pulsed fiber lasers in various power configurations from 20W – 200W, suitable for micro-drilling and high volume drilling.
