Co2 Laser Beam Attenuator

The attenuator uses brewster plates mounted in a vee configuration to eliminate lateral beam offset.

Co2 laser beam attenuator.

The polarizers are housed in a specially designed optomechanical holder mounted together with a precision kinematic adjustable waveplate holder. Laser beam attenuators our laser beam attenuators provide high resolution intensity control without introducing a gradient in the intensity distribution or a change in the beam propagation direction. Continuously variable attenuation and defined polarization for co 2 laser beams a proprietary lasnix design enables a near perfectly transmitting linear polarizer with 40 db rejection. Both the polarizer and the 1 2 wave plate are rated for 500 w cm2damage threshold.

The sa15 laser attenuator is intended to control the transmitted power of small medium co2 lasers in order to assist processing. The maximum beam diameter that the attenuator can accept is defined by the 10 mm clear aperture of the polarizer. Each consists of two znse brewster plates mounted in a vee configuration to eliminate lateral. Our manual attenuators allow the user to externally vary the power delivered from the laser.

The variable attenuators provide highest reproducibility for laser processes. In order to avoid beam clipping we recommend a maximum beam diameter of 5 mm. We supply co2 compact manual attenuators that allow you to vary laser output power. The filling gas within the discharge tube consists of around 10 20 carbon dioxide co 2 around 10 20 nitrogen n 2 a few percent hydrogen h.

The active laser medium laser gain amplification medium is a gas discharge which is air or water cooled depending on the power being applied. 1 attenuators intended to control the transmitted power of co2 laser beams 2 isolators for stopping unwanted back reflections from reaching the laser. The units described in data sections 79 xx may in general be used in either role. It has stronger absorption in many flms polymers pcb dielectrics ceramics and composites.

The enhanced version of the attenuator incorporates a rotating quartz λ 2 phase waveplate and one or two thin film polarizers that separate s polarized and p polarized beams in parallel directions. Industrial laser solutions may june 2015 signifcantly different interactionscomparedto co 2 laser output simply due to the different absorption coeffcients. Very low attenuation of the 5 6µm laser light in chalcogenide and heavy metal fuoride.

The plates may be of standard uncoated or enhanced type. We also offer laser beam attenuation kits for ultrafast laser pulses.
