Notizen: Abstract Broadband high level squeezing was clearly observed from 100 kHz to 80 MHz using crystals Ba2NaNb5O15 of 5 mm length, MgO:LiNbO3 of 19 mm length and KNbO3 of 5.8 mm length. Maximum noise reductions detected on a spectrum analyzer were −1.2 dB (−24%), −1.25 dB (−25%), and −1.8 dB (−34%) for the three crystals, respectively. The maximum squeezing is limited mostly by “optical index damage” of the parametric crystals. A detailed analysis of the beam parameters traced along the pump beam, squeezed vacuum, etc. is given. A detailed discussion on the evaluation of the initial squeezed level is given. A preliminary experiment with compressed laser pulses to avoid the optical damage is also described.
