HPC Laser Ltd (Laserscript) co2 Lasers RF and Glass Tubes

Lasers RF and Glass Tubes

 

CO2   (carbon dioxide) lasers emit invisible radiation in the infra-red region of the spectrum, wavelength 10.6 microns. There are several types mainly RF laser tubes, including solid state versions which cost typically £3k -£5k and have lifetimes of the order of 6 -10,000 hours. We can supply these already fitted to our machine, typically doubling the cost of a 600 x 900 mm bed cutter/engraver. They are cooled by blowing air rapidly over them and can thus be noisy. Obviously they cost several thousand pounds to replace and re-gas at £1800 -£2000 which with a school budget has been hard to find for some of our customers.
The lasers we usually use are made of glass and can be replaced for about £250. They last typically 1500 hours but can last much longer. Seven years ago we supplied a machine fitted with such a laser and it is still in regular use, for several hours each day. The tube fitted to a new machine is guaranteed for three months and can be fitted by a reasonably skilled person as, apart from the mechanical holding system, it only requires two simple joints.
The joints are best sealed with a special silicone compound to reduce the chance of high voltage breakdowns. Glass tubes are water cooled, using a simple system with a small pump and reservoir in which the water is allowed to cool before re-entering the laser. For machines used intensively, say several hours each day, a water chiller will be needed, ours have a refrigerant and radiator to chill the water reservoir.

We now can offer a long life selection of tubes with 80watt,100watt,150watt with a lifespan of 10,000 hours this is a first in the U.K with a competitive price of less than £1500.00 to upgrade with tube and power supply.
