few-cycle™ compact vacuum beam routing

High power and energy beams are prone to detrimental effect while propagating though air, whether because of a Raman effect, water absorption, beam self-focusing or other effects. This results in pulse lengthening, modification of the focal spot shape and quality, etc

The ultra-compact Tiny Cube beam routing system and the Vacube vacuum chambers offer full control of the beam steering both under vacuum and overpressure. ​​ ​​​

  • chambers with different volumes can fit:

    • from a single mirror mount

    • to multiple mirror mounts, e.g. chirped mirrors with up to 40 bounces

  • compatible with any other vacuum equipment through KF connections. Flange size options range from KF25 to KF75

  • centred and off centred connection

  • telescoping

  • electrical feedthrough connection

​The tiny cube™ ultra-compact vacuum beam routing 

Inner volume: 5 cm x 5 cm x 5 cm

Fits:

  • one mirror mount and one lens/window mount or

  • one camera

Lego-like flanges from 6 sides:

  • feedthrough for control of an optical mount

  • KF25 and KF40 connection

  • connection for a window (Ø1'' and Ø2'')

Full control of the beam steering both under vacuum and overpressure. The tiny cubes can be stacked for telescoping and raising the beam height.

Vacube chamber enables beam routing both under vacuum and overpressure - maximally compact & maximum access. The idea is to allow optical adjustment with free access to the mounts without the usual restrictions of a vacuum chamber. How?

By separating the steps of optical alignment and vacuum engineering. Once the adjustment is completed, the vacuum chamber can be “slipped over”. Different vacuum chambers can be freely connected with our length-adjustable vacuum telescopes. Even with the completely connected vacuum setup in place, the beam path can still be fine-tuned thanks to a top-access to the optics. Once perfectly aligned, the unit is closed with its transparent lid and pumped down. The clear aperture of the vacuum tubing is 75 mm which almost the same as the foot-print of the vacuum chamber. This aspect ratio provides maximum freedom on minimum space.

​The vacuum beaming™ Assemblies

4-axis manual control of the beam path under vacuum. Yaw, pitch, rotation and position adjustments are possible with a highly stable flexure mount. Supports up to 3” substrates. Flange type: KF 50. Pressure down to 10^-6 mbar.
