Diode: The latest technology of laser cutting guarantees precision, speed, efficiency and sustainability. In Ontario, the laser cutting technology landscape is shifting towards fibre lasers and diode lasers, offering advantages like high precision, speed, and versatility.
The increased demand for high-power laser diodes has had a significant impact on Ontario’s industries. Its precise performance provides precise results with less effort and time consumption as compared to traditional methods.
As industries like manufacturing, healthcare and telecommunications are continuously adopting technologies, the need for powerful and reliable laser diodes is surging. Fibre-coupled high-power laser diodes are especially valuable because they offer exceptional energy.
What is a Laser Diode?
It is a semiconductor device that emits coherent light when an electric current is passed through it. It utilises a p-n junction to produce laser light through stimulated emission, where photons stimulate the emission of more photons, resulting in a highly focused, monochromatic laser beam. We have listed different types of laser diodes below. Take a look and then make your decision:
1. Double Hetrostructure (DH) Laser Diode
These diodes have a layered structure with a smaller bandgap material sandwiched between two larger bandgap materials, which helps confine both charge carriers and light.
2. Quantum Well Laser Diode
Quantum wells, which are thin layers of semiconductor material, are utilised in this to enhance performance characteristics such as lower threshold current and higher output power. The quantum well is a very thin middle layer in the diode, and the quantum energy is used to convert electrons from higher energy to lower energy.
3. Separate Confinement Heterostructure Laser Diode
Along with three layers, there are two additional layers. These layers have a lower refractive index and combine the benefits of both DH and quantum well structures.
4. Vertical Cavity Surface-Emitting Laser Diode
In this type, light is emitted from a small hole in the semiconductor chip and resonates, and the optical cavity is along the axis of the current flow.

What is a Laser Fibre?
A special type of optical fibre has its active gain medium in this. This fibre is typically doped with rare-earth elements, which allows it to amplify light when pumped with a laser diode.
If you want efficient, compact and high-power, high-quality laser beams, these lasers are ideal for your industry, also they are versatile for various applications.
The rare-earth elements doped in this laser, when excited by pump light, emit photons that amplify the laser beam. A Laser diode provides the initial light (pump light) that excites the rare-earth ions in the fibre.
The doped fibre is placed within an optical cavity formed by mirrors or other reflectors. These reflectors ensure that the amplified light bounces back and forth, further increasing its intensity.
Laser diode or laser fibre, which one is better?
It can be easy to identify which one would be ideal for your needs, you need to look at the features, including efficiency, precision and personalised results.
Fibre lasers have become the choice of many individuals because of higher power, better beam quality, and greater flexibility. Fibre lasers offer significantly higher power output and faster cutting speeds compared to diode lasers, making them ideal for demanding industrial applications like metal cutting. A highly focused and stable beam is produced, resulting in precise cuts and engravings.
Fibre lasers can cut materials at high speeds, boosting production and reducing cycle times.
Their high energy efficiency results in lower power consumption compared to other laser technologies. This combination of speed and efficiency translates to lower operational costs and increased productivity.
Talking about lasers, they are cost-effective and customizable. These lasers are generally less expensive compared to fibre lasers, making them a good option for hobbyists and small businesses. lasers are easily customizable and can be integrated into various systems, offering flexibility in custom applications.
If diode lasers are your choice, then these are relatively small and compact, making them suitable for applications where space is limited.
Depending on your industry needs, you can adopt any of these lasers and make your work more efficient and productive. These lasers can provide customisable and speedy results, which can eventually increase efficiency, and your workload will be less.
