Generation of coherent blue light via bichromatic pumping in cesium
In this study, we investigate a generation of coherent blue light (CBL) via four-wave mixing (FWM)-based up-conversion processes in cesium (Cs) vapor. A bichromatic pumping scheme with 852- and 917-nm lasers drives the Cs atoms to the 6 D5/2 excited level, followed by cascaded decay of 6 D5/2 → 7 P3/2 → 6 S1/2, producing 456-nm CBL …

mixer that provides the "LO + IF" signal in figure 3 has a power limitation of about +I4 dBm. Therefore, the DRO signal is attenuated from its normal +24 dBm level to +11 dBm with an adjustable DDS level up to +3 dBm. The LO + IF signal is amplified to approximately its previous normal level of +24 dBm, after cable, mixer, and isolator losses. IV.

Time and Frequency from A to Z, P | NIST
The time interval for 1° of phase is inversely proportional to the frequency. If the frequency of a signal is given by f, then the time tdeg (in seconds) corresponding to 1° of phase is tdeg = 1 / (360f) = T / 360. Therefore, a 1° phase shift on a 5 MHz signal corresponds to a time shift of 555 picoseconds. This same answer can be obtained ...
