Squeeze Laser


The Squeeze Laser is a compact, table-top system (footprint 41 cm x 61 cm) designed for the generation of continuous-wave squeezed vacuum states at either 1550 nm or 1064 nm. This advanced system achieves squeezing levels of up to 10 dB in the MHz frequency regime, with the flexibility to extend the squeezing regime down to the kHz range through a dedicated locking scheme. The output is a high-quality, free-space TEM00 spatial mode, ensuring excellent beam characteristics.

The control electronics are integrated in a compact 6U rack, featuring an intuitive touch screen interface for seamless operation and monitoring of the Squeeze Laser.

Beyond standard squeezed vacuum generation, our technology enables the creation of entangled beams derived from squeezed vacuum states. Furthermore, Noisy Labs' Squeeze Lasers can produce indistinguishable photon pairs in TEM00 beams at significantly reduced pump powers.

We specialize in tailoring our Squeeze Laser systems to meet specific research and application requirements. If you are interested in customized solutions, including entangled beam generation or photon pair sources, we encourage you to contact us to discuss your project needs and explore how our technology can advance your work.
