Scratching the surface of laser ablation (brochure)

Laser ablation is the controlled removal of material from a solid surface by irradiating it with a laser beam.

Industries including automotive, printing and textiles use laser ablation for surface cleaning or surface modification such as texturing to allow adhesive bonding.  It is an attractive technique because it eliminates the need for harmful chemicals and consumables.  A CO2 or femtosecond laser source can remove a coating or the base material itself. By breaking the molecular bonds within the material and vaporising it the contactless laser process ensures that the right amount of material is removed.

This brochure outlines the benefits of using lasers for surface-processing applications.

The principle of sealed CO₂ lasers

A sealed CO2 laser consists of two slab electrodes inside a sealed tube.  The tube is filled with a gas mixture including carbon dioxide, nitrogen and helium.

The electrodes are water cooled.

A mirror is placed at each end, forming an optical resonator.  One of the mirrors is partially reflective, allowing light to exit the resonator.

RF power is applied to the electrodes, exciting a gas discharge between them.

As the gas molecules lose energy, photons are emitted.  The photons travel back and forth within the resonator, stimulating the emission of more photons as they collide with the excited molecules.

As the photons all travel in the same direction, in phase and with the same wavelength, a laser beam is produced.

Laser-cut notepad reveals 3D design

Chinese end user MociWorld is making eye-catching 3D notepads using Luxinar’s SR laser sources.

Paper and card generally react well to the CO2 laser wavelength range, so the cutting process is fast and reliable, and quality is good; it’s ideal for precision processing, and the creator’s design can be a 1:1 accurate presentation, even with complex patterns.

In addition, while processing the paper material, our CO2 laser brings a great result: a very clean cutting edge without yellowing, and delicate pieces are not deformed or distorted during cutting.

Luxinar focuses on manufacturing innovations at FABTECH 2022

Leading laser manufacturer Luxinar is focusing on innovations for the manufacturing industry with its OEM and SR series of sealed CO2 laser sources on booth B9653 at FABTECH, taking place November 8-10, 2022 at the Georgia World Congress Center in Atlanta, GA.

Luxinar specialises in the manufacture of laser sources for industries throughout the world including automotive, electronics, packaging and textiles.  Its CO2 lasers are available at three wavelengths, 10.6, 10.25 and 9.3 microns, and are widely employed for cutting, perforating, marking and scribing of a variety of materials such as plastics, metals, wood, paper and glass.

The OEM series of CO2 lasers with a power range up to 1000W represents a compact solution that can be easily integrated into industrial processing production lines both with and without covers.  The range includes an integrated RF power supply, enabling the laser to produce short optical pulses with high peak power or quasi-CW output and it can operate safely over a wide range of pulse widths and frequencies including through the acoustic regions and a broad range of coolant temperatures.  There is also the option for an absorbing thin film reflector (ATFR) to prevent back reflection.

The SR series of sealed CO2 laser sources have a power range up to 250W and a rating of IP66; this means they are ideal for the harshest of industrial environments to ensure a high level of protection against water and dust ingress. The product range is constructed for ease of installation, use and maintenance in laser-based processing machines. Each unit has a compact and lightweight mechanical design with a straightforward DC power supply connection, easy-to-understand control interface and digital diagnostics with enhanced LED. The same output beam position allows for power upgrades with minimal design changes and an integrated RF power supply that is replaceable in the field ensures that production downtime is minimal.

“We are looking forward to showcasing our range of laser sources at FABTECH,” said John Podwojski Regional General Manager of Luxinar’s USA office. “This allows us to present our CO2 lasers and the benefits of working with a company that has nearly 25 years of experience in laser technology.” 

Luxinar leads the charge at The Battery Show 2022

Hot on the heels of its USA office opening in June, leading laser manufacturer Luxinar is exhibiting the company’s well-established OEM and SR series of sealed CO2 laser sources on booth #1855 at The Battery Show North America, taking place 13-15 September in Novi, MI.

Luxinar specialises in the manufacture of laser sources for industries throughout the world including automotive, electronics, glass, packaging and textiles. Its CO2 lasers are available at three wavelengths, 10.6, 10.25 and 9.3 microns, and are widely employed for cutting, perforating, marking and scribing applications.  Specifically for the battery industry, Luxinar’s laser sources are used for a variety of processes including hairpin coating removal, battery case ablation and electronic component marking.

Luxinar – INGENUITY AMPLIFIED

See Luxinar at Laser Taiwan 2022

Global laser leader Luxinar is delighted to be supporting its agent ASTC as it exhibits the manufacturer’s SR AOM series of sealed CO2 laser sources on stand 1216 at Laser & Photonics Taiwan in Taipei, taking place 24-27 August.

Luxinar specialises in the manufacture of laser sources for industries throughout the world including automotive, electronics, glass, packaging and textiles. Its CO2 lasers are available at three wavelengths, 10.6, 10.25 and 9.3 microns, and are widely employed for cutting, perforating, marking and scribing applications. Its femtosecond laser sources are offered at three wavelengths – 1030nm, 515nm and 343nm – and are targeting applications in the electronics, medical device, printing, security and automotive industries.

The SR AOM series, with power ranges up to 150W, is designed to address a wide range of high-precision applications that require a reduced heat affected zone (HAZ), such as multilayer thin film cutting for the display market and high resolution/speed marking. This CO2 laser with integrated acousto-optic modulator (AOM) creates optical rise and fall times of less than 1µs which can minimise unnecessary heat energy from typical pulse rise/fall times of approximately 60µs.

The LXR® series represents Luxinar’s first range of femtosecond laser sources, a technology that has revolutionised materials processing due to its large dynamic range of average powers (up to 120W), pulse energies (up to 100µJ) and pulse repetition frequencies (single shot-40MHz).  Its pulse on demand allows pulses to be evenly spaced regardless of motion speed and the extremely short pulse width of the laser (900 ± 100fs) virtually eliminates heat diffusion to the surroundings of the processed region. These enable ultrahigh precision micro- and nanofabrication of various components with high throughput and repeatability.

“We are looking forward to having a face-to-face presence once again at Laser Taiwan,” said Patrick Kim, Regional General Manager of Luxinar’s Korea office. “This allows us to easily present our range of laser sources and the benefits of working with a company that has nearly 25 years of experience in laser technology.”

American Independence Day

To celebrate American Independence Day on the 4th of July we have created bunting by laser cutting fabric in the design of the US flag.

In our applications lab we achieved a clean cut of the stars and stripes fabric with one of our well-established SR series.  These Luxinar CO2 laser sources, with output powers of up to 250W, can cut a wide range of textiles at varying speeds and thicknesses. 

During cutting, the laser sealed the edges of the fabric to prevent fraying so there was no need for additional sewing.
