Co2 Laser Beam Temperature

Winter maintenance of co2 laser cutting machine.

Co2 laser beam 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. Housing temperature will exceed 40 c above 2 w input power. Interesting notes on laser technology. I haven t really been able to find what the optimal operating temp range for a sealed co2 laser is.

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 carbon dioxide laser co 2 laser was one of the earliest gas lasers to be developed. Caution should be taken when using this beam trap with laser beams above 2 w as it will become hot to the touch. The mean temperature of 90 plane is 397 8 and 45 plane is 960 9.

The closer location from the laser heating is defined the higher mean temperature is occurred. Total integrated backscatter as a fraction of entrance beam power. 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. 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. For each end cap splice the beam profile of the hollow core fiber has been preserved. 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. The ratio of output power to pump power can be as large as 20.

Carbon dioxide lasers are the highest power continuous wave lasers that are currently available. By a carbon dioxide laser tube it is water cooled we had better control the temperature 25 degrees because at this temperature when the energy of the strongest. Splice repeatability was achieved by using temperature and beam position control for the laser splicing process. 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.

In fact the anti high temperature in summer and freezing in winter are important. That a laser beam can have no temperature. So now that my laser cutter is up and running i ve started to notice the effect of water temperature on laser output. It was invented by kumar patel of bell labs in 1964 and is still one of the most useful.
