IMPACT TEA CO2 Lasers

CO2 lasers from GSI Lumonics for marking, drilling, material processing and non destructive testing LightMachinery's IMPACT 2000 lasers are designed primarily for the fine processing of non-metallic materials. Drilling and machining are typical applications for these lasers. A unique capability of the IMPACT laser is the ability to drill through non-metallic layers on a metal substrate with no damage to the underlying metal layer. This capability proves very effective in applications such as printed circuit board drilling, wire stripping and mold cleaning.

The IMPACT 2000 series of lasers all incorporate high reliability SSM switch technology as well gas filtering systems to ensure very high uptimes and low maintenance even at continuous 75W power delivery 24/7.

The IMPACT 3000 series lasers are high-power (up to 300 Watts) short-pulse CO2 lasers for surface layer removal and cleaning, non-destructive testing, and photochemistry. Applications include polymer removal, mold cleaning, paint stripping, Lidar and laser
isotope separation. The highest repetition rate model (3400) is intended primarily as a source for laser ultrasound testing.

The fully configurable IMPACT 4000 series lasers are designed for more scientific and specialized applications. The short pulse of the thyratron switched IMPACT 4000 is ideal for ultrasound applications as well as applications in infrared chemistry. The IMPACT 4000 can be configured with a tunable option and set up in a Master Oscillator Power Amplifier, MOPA, configuration with additional amplifiers to achieve the right power at the right wavelength for your application.

IMPACT Applications  
Slow release tablet drilling SEM picture of a beautiful round 50 micron hole drilled in a printed circuit board. These via holes are drilled through a top copper layer, through the board insualtion down to the copper layer below. Once the hole is plated it creates an electrical connection between tracks on different board layers.

Impact TEA CO2 lasers have proven to be a uniquely valuable tool for wire-stripping and other fine processing applications in medical device manufacturing, offering an extremely cost-effective alternative to excimer lasers.

Energy Density Calculator

The high absorption of the 9.3 µm wavelength in most polymer materials, combined with the short pulse duration of TEA CO2 lasers, means that Impact lasers mimic the photo-ablative excimer process of excimer lasers, at ~50% of the capital cost, <10% of the operating cost, and generally higher throughput.

Tablet drilling system In wire stripping applications it is often advantageous to split the laser beam into 2 or 4 beams in order to remove the micro-wire insulation without the need to move or rotate the wire. 2 focusing lenses (in black threaded barrels) are visible in this photo.
