Variable Laser Beam Attenuator

They provide the highest degree of reproducibility for laser processes.

Variable laser beam attenuator.

The avacs includes power supply control display operation elements starting routine limit stop device computer interface and water cooling. Our variable attenuator kit is an easy to use kit for the continuous attenuation of the laser output power.

Qty 1 1 525 00. Laseroptik offers avacs automatic variable attenuator control system. The newly developed laser attenuator allows computer controlled attenuation of a monochromatic light source from 1 99 see figure 1 within the wavelength region 550 nm to 1000 nm. Motorized variable attenuator for femtosecond and nd yag laser pulses 990 0072m motorized variable attenuators with ø 22 mm clear aperture composed of thin film polarizers half waveplates and opto mechanics for easy setup.

Attenuators consist of thin film polarizer high performance waveplate and precision opto mechanics. The variable laser attenuators va are designed for precise precision adjustment and stabilization of laser powers. Cos 2 q i i o 1 e v e e o f f l a s e r b e a m l a s e r p o l a r i z a t i o n e figure 2. 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.

Thorlabs variable beamsplitters allow the user to continuously vary the transmitted intensity of a linearly polarized beam of light. The attenuator is then given by laser 1 2 wave plate polarizer p s b eam stop figure 1. Motorized rotation of the waveplate allows continuous variation of the intensity ratio of the output beams. The laser attenuator incorporates technology derived from a joint collaboration between edinburgh biosciences ltd and delta optical thin film a s.

We also offer laser beam attenuation kits for ultrafast laser pulses. Schematic of variable attenuator for lasers. The electric field of a laser beam decomposes into two orthogonal components. Tye are typically used for excimer and yag laser wavelengths.

Step add to. To adjust the laser power down to the level required typically users are forced to use either neutral density filters or other devices to reduce the pump power going to an experiment. Zero order 1 2 wave plate. The unit is driven by a stepper motor and can be controlled manually or by a computer.

These techniques do not typically allow for continuous control of the laser power.
