The active laser medium laser gain amplification medium is a gas discharge which is air or water cooled depending on the power being applied.
Co2 laser beam attenuator.
It has stronger absorption in many flms polymers pcb dielectrics ceramics and composites.
The variable attenuators provide highest reproducibility for laser processes.
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.
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 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.
Both the polarizer and the 1 2 wave plate are rated for 500 w cm2damage threshold.
We supply co2 compact manual attenuators that allow you to vary laser output power.
The units described in data sections 79 xx may in general be used in either role.
We also offer laser beam attenuation kits for ultrafast laser pulses.
Our manual attenuators allow the user to externally vary the power delivered from the laser.
Industrial laser solutions may june 2015 signifcantly different interactionscomparedto co 2 laser output simply due to the different absorption coeffcients.
The attenuator uses brewster plates mounted in a vee configuration to eliminate lateral beam offset.
Showing 44 products in 4 families.
The plates may be of standard uncoated or enhanced type.
The stabilization of pulse energies in production processes is their main use.
Sintec optronics one stop shop for lasers laser parts machines 65 63167112.
1 attenuators intended to control the transmitted power of co2 laser beams 2 isolators for stopping unwanted back reflections from reaching the laser.
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.
The polarizers are housed in a specially designed optomechanical holder mounted together with a precision kinematic adjustable waveplate holder.
In order to avoid beam clipping we recommend a maximum beam diameter of 5 mm.
Each consists of two znse brewster plates mounted in a vee configuration to eliminate lateral.
