The laser machines will be equipped with unique configurations (only for machines on www.cloudraylaser.com) which have high stability and marking efficiency. According to the actual use and market share, the cutting performance and service life of thermally stimulated fluorescent tubes are worthy of recognition. It occupies a large market in the world and is a great brand. EFR Laser tube The video below shows the whole process of building and testing the tube. Initial tests were disappointing, but with a lot of tweaking and the addition of a much bigger neon sign transformer to power the tube, the familiar bluish-purple plasma made an appearance. Further fiddling with the mirrors revealed the least little bit of laser output — nowhere near enough to start cutting, but certainly on the path to the ultimate goal of building a laser cutter. From these data, we can conclude that the heat dissipation in the tube is somewhere around 330-350 watts.

collisionally de-excites by transferring its vibrational mode energy to the CO 2 molecule, causing the carbon dioxide to excite to its {v3(1)} (asymmetric stretch) vibrational mode quantum state.

(F2 CO2 laser tubes require a 4mA current). Our laser tubes can carry out high-frequency pulse engraving. EFR A Series Laser Tube Patel, C.K.N.; etal. (1965). "CW High-Power CO 2-N 2-He Laser". Applied Physics Letters. 7 (11): 290. Bibcode: 1965ApPhL...7..290P. doi: 10.1063/1.1754264.As the tube degrades, the power output gradually decreases which leads to the user either increasing the power or slowing the cutting speed. Resulting in the tube running harder or longer than necessary. Some tubes contain a catalyst that recombines the Carbon Monoxide and Oxygen, replenishing the lost CO2, but some of the free oxygen can collect on the cathode (the low voltage end of the tube) giving it a yellow tint. This is how manufacturers can determine if the tube has been overdriven and refuse any warranty claim. cutting and structuring plastic materials, wood, die boards, glass pieces, etc., which exhibit high absorption at 10.6μm, mostly applying moderate power levels of 20–200W In the golden autumn of September, with the increasingly cooler weather, SPT Laser sincerely invites you to visit the four major domestic exhibitions to learn and communicate together and discuss laser application technology. If the above methods do not work effectively, professionals are required, who will use a cotton swab dipped in ethanol to clean the lens in a rotating fashion away from the center, outwards to the edge.

The 70 W is definitely an investment and best for professionals that work on larger-scale projects. The machine itself is also quite big, so make sure there’s room for a 126 x 87 x 92 cm cutter. LONGER SERVICE LIFE】- Our service life of discharge tubes coated with special catalysts is much improved. Compared with other laser cutting tubes, our 50W co2 laser can last longer. Because CO 2 lasers operate in the infrared, special materials are necessary for their construction. Typically, the mirrors are silvered, while windows and lenses are made of either germanium or zinc selenide. For high power applications, gold mirrors and zinc selenide windows and lenses are preferred. There are also diamond windows and lenses in use. Diamond windows are extremely expensive, but their high thermal conductivity and hardness make them useful in high-power applications and in dirty environments. Optical elements made of diamond can even be sand blasted without losing their optical properties. Historically, lenses and windows were made out of salt (either sodium chloride or potassium chloride). While the material was inexpensive, the lenses and windows degraded slowly with exposure to atmospheric moisture. The laser resonator mode is a standing electromagnetic wave. The resonator is the laser basis. Its size depends on the radiation wavelength. Particularly, the resonator length should be divisible by ½ of the wavelength. It is equipped with a dust cover design for the laser light outlet, which is suitable for a variety of industrial environments. EFR X Series Laser Tube
