Co2 Laser Beam Attenuator
We also offer laser beam attenuation kits for ultrafast laser pulses.
Co2 laser beam attenuator. 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. The maximum beam diameter that the attenuator can accept is defined by the 10 mm clear aperture of the polarizer. 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 variable attenuators provide highest reproducibility for laser processes.
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. In order to avoid beam clipping we recommend a maximum beam diameter of 5 mm. The sa15 laser attenuator is intended to control the transmitted power of small medium co2 lasers in order to assist processing.
The active laser medium laser gain amplification medium is a gas discharge which is air or water cooled depending on the power being applied. Each consists of two znse brewster plates mounted in a vee configuration to eliminate lateral. Both the polarizer and the 1 2 wave plate are rated for 500 w cm2damage threshold. The attenuator uses brewster plates mounted in a vee configuration to eliminate lateral beam offset.
We supply co2 compact manual attenuators that allow you to vary laser output power. The stabilization of pulse energies in production processes is their main use. 1 attenuators intended to control the transmitted power of co2 laser beams 2 isolators for stopping unwanted back reflections from reaching the laser.

Industrial laser solutions may june 2015 signifcantly different interactionscomparedto co 2 laser output simply due to the different absorption coeffcients. Showing 44 products in 4 families. 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. The polarizers are housed in a specially designed optomechanical holder mounted together with a precision kinematic adjustable waveplate holder.
To compensate the beam displacement generated by the dielectric filter a transparent second optic is also employed. The plates may be of standard uncoated or enhanced type.
