Download or read book Saturated Absorption Frequency Locking and Second Harmonic Generation for Narrowband Entangled Photon Pair Generation written by Lluís Danús Amengual and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of two locking systems for light sources desired to generate narrowband photon pairs is under study. First a DBR laser will be locked to the D1 transition frequency of Rb 87 using a Doppler-free Saturated Absorption Spectroscopy. Afterwards the frequency-locked light will be doubled in a nonlinear PPKTP crystal resulting in a frequency stabilized source at 397.5 nm.
