Product Portfolio
Industrial Fiber Laser Range

- redENERGY® and redPOWER® Fiber Lasers
Our redENERGY® and redPOWER® Fiber Laser range comprises fused
components, meaning the performance is not dependent on the alignment of
rods and mirrors, nor can dirt or dust ingress the resonator and deteriorate
its properties. For manufacturers using our Lasers, this eliminates the need
for time-consuming, routine maintenance.
The absence of water-cooled pump chambers negates the risk of leaks that
could cause the rods to fail, avoiding service costs. In addition, the use
of a doped fiber as the gain medium in Fiber Lasers results in intrinsically
stable beam quality, regardless of any heat load, with high brightness, and
even in fundamental mode if designed accordingly.
Our Fiber Lasers can be supplied with patented Luminator™ fiber-delivery
options. These ensure safe and reliable 3D manipulation of the Laser beam
and positive material processing results.
Our Fiber Laser range includes both rack-mountable and OEM units for your
fiber laser system, offering both air and water cooled options, depending on
the respective output powers.

Laser Ablation
- Laser ablation is the process of precision layer removal by a laser. This could be the removal of a wide-range of materials ranging from solid metals, ceramics and industrial compounds. Ablation is popularly used in applications such as elements used within electronic products (e.g. semi-conductors and micro-processors) by irradiation with a Laser beam. The absolute precision of Fiber Lasers comes to the forefront with laser ablation, a process which has many similarities to some of the laser cleaning processes. The general difference between laser ablation and laser cleaning is that ablation seeks to remove material, whereas cleaning aims to clean the material.

Additive Manufacturing
- Additive manufacturing is the process of building up a 3D component by adding layer upon layer of material deposit. It is also commonly described as “3D printing”. Using a combination of special machines – often referred to as printers – and computer software, complex shapes can be created. It is a technology that has been in existence for 30+ years, but it’s only in recent years that the technique has been more widely used for its versatility and excellent return on investment (amongst other reasons).

Laser Cleaning
- Laser cleaning is the process by which contaminants, debris or impurities (e.g. carbon, silicon and rubber) are removed from the surface of a material by using laser irradiation. This is a low-cost and environmentally-friendly laser application technique, which is in widespread use throughout global industry.
There are two types of laser cleaning process, which are typically used:
- One which is the removal of a layer on the surface of a material,
- While the second is the removal of the entire upper layer of a
material.

Laser Cutting
- Laser cutting is a process where a material is cut through the use of a laser beam. This can be for small & fine materials or materials with a much greater level of thickness (e.g. metal sheets). Laser cutting simply involves the use of a focused laser beam (e.g. pulsed or continuous wave) to cut a wide range of materials to a high-level of accuracy, using a process, which is highly repeatable.
The laser beam can easily be programmed to precision cut a diverse range of thicknesses and materials (e.g. metals (including reflective metals such as copper and aluminium) – brass, tungsten, steel, pewter and titanium etc.), gemstones (e.g. diamonds), ceramics, graphic composites, silicon and many types of plastics).
Even the most complex, awkward and intricate of shapes can be accurately cut through fiber laser cutting as the user has total control over the beam intensity, duration and heat input. Laser cutting has some similarities to other laser-based processes such as engraving and drilling, which also use a focused laser beam to effectively make designed cuts into a material.

Laser Drilling
- Laser drilling is the process of creating “popped holes” or “percussion drilled” holes in a material, which is achieved by pulsing a laser beam on a particular area repeatedly. The material subject to laser drilling is vaporised and melted layer by layer until drill holes are created. This process will differ depending upon the thickness of the material, the number of holes that need to be created, and the size (width and depth) of these holes. Drilling with lasers is renowned for its high levels of precision, which can be managed carefully by monitoring beam intensity and duration. The entire laser drilling process is achieved without any direct contact with the material surface. Laser drilling can be compared to both laser ablation and laser cleaning, which remove areas of a material through the use of focused heat from lasers.

Laser Engraving
- Laser engraving is the process of removing a portion of material to leave an engraved mark which is visible beneath. The engraving process is produced by the Laser beam removing material to create a mark, where the Laser acts like a chisel and blows away selected areas of the subject material. It is a subset process of laser marking where the object is actually marked beneath the surface and is the most common of all the laser marking applications. The depth of the engraving made will depend on the dwell time as well as the type of material being used. It can be used on a variety of materials, including ceramics, plastics and all forms of metal. As well as marking, the laser engraving process can also be compared with ablation and etching, which work in similar ways.

Laser Marking
- Pulsed Fiber Lasers are renowned for their versatility with laser marking being one of the most popular applications. Although similar to laser engraving, the appliance of a mark is at a surface level, whereas engraving is a mark with depth. Laser marking is the process where a material, which can be anything from ceramics, plastics, metals, LEDs, rubber, graphic composites, etc. is marked or labelled with a simple black mark, or in colour (depending upon the material).

Laser Welding
- welding is an application that businesses simply can’t afford to ignore for quality and cost reasons.
Regardless of the material, thickness or dissimilarity of metals, welding is an application that both our Pulsed and Continuous Wave (CW) lasers can achieve. From fuel cells and batteries through to fine wires for medical device manufacture, if your aim is to perfect your processing techniques then look no further than our range of Pulsed and CW Fiber Laser solutions. These lasers can also be used for many other applications too such as drilling, marking, cutting, etc. all of which can be programmed into a seamless process flow.
Benefit from our “fit and forget” technology, which requires zero maintenance and requires no re-alignment. Our fiber lasers are supplied as complete units in 19” configurations and for most customers save large amounts of space compared to previous technologies.
