Laser

PEG specializes in shrinking glass and quartz tubing into precision bore tubing. Additional special capabilities include: glass fabrication; glass finishing; glass machining; and glass blowing used to produce a variety of glass components.

Typical Components: Glass To Metal Seals – Glass To Glass Seals – Graded Seals – Glass Assemblies

Precision Electronic Glass (PEG) has been a primary OEM supplier of laser flow tubes, discharge tubes, electrode tubes, glass to metal seals, and gas port tubing, as well as gas sealed tubes. PEG fabricates custom laser glass and quartz parts for CO2, YAG, and HeNe laser components. Fabricated in PEG’s facility that meets ISO:2008 quality management standards, these glass and quartz components meet the most stringent standards demanded by laser manufacturers.

PEG uses glass-to-glass, glass-to-metal, and graded seals in fabricating custom laser glass and quartz parts for CO2, YAG, and HeNe laser components. Fabricated in facilities that meet ISO:2008 quality management standards, these glass and quartz components meet the most stringent standards demanded by laser manufacturers.

Fabrication of laser components requires the use of graded seals. A graded seal is used when two materials have different coefficients of thermal expansion. A series of intermediate sealing glasses is used between the two different glasses. The linear coefficient of expansion must be close to avoid cracking of the graded seals. PEG’s five decades of experience ensures durability and long life of the graded seals we produce

CO2 Lasers

The concept of stimulated light was first theorized by Albert Einstein in 1917. It was not until the late 1940’s and 1950’s that scientists developed a practical device which became known today as a LASER an acronym for Light Amplification by Stimulated Emission or Radiation.

The carbon dioxide (CO2 laser) was one of the earliest gas lasers. It was developed by Kumar Patel of Bell Labs in 1964. This laser quickly became the industry workhorse with its available high continuous power and efficiencies to 20%. The CO2 laser produces a beam in the infrared with principal wavelengths of 10.6 and 9.4 micrometers. The gas fill consists primarily of CO2, N2, H2 and He. Xenon is sometimes added to a sealed tube design.

CO2 lasers have found applications in industry for cutting, welding and engraving. Also, in medical uses such as laser surgery and skin treatments. The military has similarly found use for CO2 lasers as rangefinders using LIDAR.
