Laser power noise detection at the quantum-noise limit of 32 A photocurrent

Your library or personal account may give you access

Abstract

The power noise of a cw Nd:YAG laser system was measured at radio frequencies using the optical ac coupling technique. An additional mode cleaner in the setup allowed a high optical ac coupling amplification of 62.3. For the first time, to our knowledge, a sensitivity of 1.1×1010Hz1/2 relative power noise was achieved corresponding to an equivalent detected photocurrent of 32A. High precision optics experiments can utilize this scheme to improve the sensitivity of their photodetectors.
