Co2 Laser Beam Temperature

So now that my laser cutter is up and running i ve started to notice the effect of water temperature on laser output.

Co2 laser beam temperature.

A co2laser beam as an electro magnetic light wave at a wavelength of 10 600 nm contains a certain energy which is partially absorbed by the material. The antireflection ar coated end caps have a diameter of 6 mm and a length of 5 mm. The closer location from the laser heating is defined the higher mean temperature is occurred. Carbon dioxide lasers are the highest power continuous wave lasers that are currently available.

I haven t really been able to find what the optimal operating temp range for a sealed co2 laser is. In fact the anti high temperature in summer and freezing in winter are important. That a laser beam can have no temperature. Laser means light amplification by stimulated emission of radiation it can produce an intense highly directional beam of light the most popular cause of laser induced tissue damage is the thermal in nature the tissue proteins are denatured due to the temperature rise following absorption of the laser energy.

The feedback method employs a sensor for laser beam power and cmos cameras as sensors for fiber luminescence which is directly related to glass temperature. Splice repeatability was achieved by using temperature and beam position control for the laser splicing process. Performance of individual units may differ due to material variability. Caution should be taken when using this beam trap with laser beams above 2 w as it will become hot to the touch.

Winter maintenance of co2 laser cutting machine. More specifically at one stage the water loop developed a leak and the laser was running very warm and the power drop was quite significant. Heat is the random motion of matterparticles atomic or molecular particles however the laser beam itself is not made of matter but of photons the so called light particles which have no mass i e. They are also quite efficient.

Total integrated backscatter as a fraction of entrance beam power. Housing temperature will exceed 40 c above 2 w input power. The mean temperature of 180 plane from the laser heating is the lowest as 197 4 because the material removal plane is far from laser heating. The mean temperature of 90 plane is 397 8 and 45 plane is 960 9.

The carbon dioxide laser co 2 laser was one of the earliest gas lasers to be developed. Interesting notes on laser technology. For each end cap splice the beam profile of the hollow core fiber has been preserved. It was invented by kumar patel of bell labs in 1964 and is still one of the most useful.
