Laser Beam Attenuator

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.

Laser beam attenuator. The ultrafast version of the attenuator is intended for laser pulses of 100 fs. Laser beam attenuator enhanced version. The variable attenuators provide highest reproducibility for laser processes. The 248 nm attenuator can vary the output power from.

For example if the beam diameter is 1 mm the maximum laser power at the attenuator should not exceed 4 w. 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 laser attenuator allows user control of attenuation by combining the loma with a. Laser accessories manual attenuators.

In the continuously variable attenuator two polarizers can be set to continuously control the transmitted beam power and independently set its polarization. In the case of the mai tai femtosecond oscillator the beam diameter is 1 2 mm. The 193 nm attenuator can change the output power from about 20 to 85 transmission. Variable attenuators for linearly polarized laser beam 990 0070.

It incorporates a rotating achromatic λ 2 phase waveplate and two high performance broadband 72 thin film polarizers that separate s polarized and p polarized beams in parallel directions. Clear aperture 15 mm bandwidth up to 20 nm optimization reflection or transmission type configuration λ 2 zo waveplate 1x or 2x thin film polarizers. Parts list the following components are used to. Motorized variable attenuator for femtosecond and nd yag laser pulses 990 0072m divides laser beam into two beams of manually adjustable intensity ratio separated by 68 angle large dynamic range tr.

Laser beam attenuator enhanced version. Variable attenuators with ø 17 mm clear aperture composed of two thin film brewster type polarizers and a waveplate mounted into precision opto mechanics. To compensate the beam displacement generated by the dielectric filter a transparent second optic is also employed. The loma uses a wedge thin film coating design to control the intensity or power of the transmitted laser beam.

The stabilization of pulse energies in production processes is their main use. We also offer laser beam attenuation kits for ultrafast laser pulses. Beam attenuators are available for 193 nm arf and 248 nm krf excimer lasers. Attenuator design allows to control the intensity between two exit beams over a wide dynamic range.
