We carry several standard laser gas blends in stock and have the ability to custom-make or source more specialized laser gas mixes to fit your needs.

These beamsplitters have extinction ratios of >1000:1 (TP:TS). The average p-component transmission is >90% while the average s-component reflectance is >99.5% for each beamsplitter. Please see the Graphs tab for more information. The split ratio is continuously variable from 0 to 30 dB and is dependent on the polarization extinction ratio from the input PM fiber and the spectral line width when Δλ ≤ 3 nm.

It's easy to remember how laser beams work when you think about the acronym -- "Light Amplification by Stimulated Emission of Radiation." Here at Greco Gas, we talk about gas lasers, but lasers can also be made by passing the electricity through glass or crystals. They are instrumental in consumer electronics like CD and DVD players, measuring, munitions, computing and surgery.

Laser cutting equipment requires concrete gas mixtures to create the laser beam. At the Greco Gas laboratory in Tarentum, we produce gravimetric mixtures of Argon, Helium, CO2, and CO (Carbon Monoxide) in many combinations. Our component gases are UHP (Ultra High Purity) grade, producing superior beam quality.

Greco Gas can provide prepackaged or custom laser gas mixes for whatever suits your laser machine's specifications. Provide your concentration percentages specified by your laser machine manufacturer, and we can assist you in finding the right gas blend.

AssemblyThese kits include all the hardware needed for assembly and adjustment. To assemble, insert the dowel pins of the half-wave plate and beamsplitter module into the desired slots on the FiberBench; lock their positions using the 2-56 set screws and 0.9 mm hex key. The beamsplitter cube can be aligned using four 0.050" hex adjustment screws, which can then be locked in place using their locking collars and the included SPW403 spanner wrench. The X, Y, and Zθ adjusters for each FiberPort also accept the 0.050" hex key. The sensitivity of the X and Y adjusters can be varied using the two holes located on the faceplate of the FiberPorts and the 0.028" hex key. The orientation of each FiberPort may be locked using the included 0-80 locking screws and the 0.050" hex key. Care must be taken when locking the FiberPort to avoid misalignment or damage. In most cases locking is not required. Please reference the FiberPort Manual for instructions. The rotation of the half-wave plate may be locked using the screw located at the top of the wave plate and the 0.050" hex key.

There are several basic ways that laser gas can be supplied. Individual cylinders are a safe, easy and economical way of providing gas to the laser machine. One thing to keep in mind is that there can be an interruption in gas flow when changing the cylinders or cluster of cylinders.

Let's discuss how lasers work because this is some cool science! Gas lasers are made by passing an electric current through one of several certain noble gases or gas mixtures. The electricity excites the electrons within the gas's atoms and elevates them to highly energized orbits around their atoms' nucleus. When the electrons return to their normal, lower energy state, the electrons will emit particles of light called photons.

These Variable Polarization Beamsplitter Kits are based on Thorlabs' FT-51X60 Multi-Axis FiberBench. A PM fiber can be attached to the input FiberPort, which collimates the output. The FiberPorts included with these kits have wide key slots. The polarization of this beam is then rotated with a half-wave plate. By changing the orientation of the wave plate, the ratio of the vertical to horizontal State of Polarization (SOP) is changed, which then affects how much signal is transmitted and reflected through the polarizing beamsplitter cube.

What's neat about photons is that the light they emit is a consistent wavelength dependent on the amount of energy that was released. Since all the energy is of the same wavelength, only one color in the color spectrum will be emitted. Emitting variations in wavelength produces natural light, but a uniform wavelength will create a single color, such as red or blue. The other distinct factor about laser light is, it is directional, making a beam of consistent light that doesn't diffuse; lasers can keep a focused beam for miles, a characteristic termed as "coherent."

Another supply option is a cylinder bank system. This method is recommended for wall mounting and uninterrupted operation. The benefit of this is that the switchover is performed manually or automatically.
