Nettet31. mar. 2024 · The frequency noise at 1 Hz offset is suppressed by 11 orders of magnitude from that of the free-running diode laser down to the cavity thermal noise limit near 1 Hz /Hz, decreasing to 10 Hz /Hz at 4 kHz offset. Nettetfrequency noise on self-heterodyne linewidth measurements is needed so that this characterization technique can provide the information needed for accurate predictions of system perfor- mance. Recently, Kikuchi and Okoshi have noted the broaden- ing effect of 1 /f frequency noise on the laser diode lineshape NettetThe frequency noise for E15, X15 (stabilized version of E15), and C15 fiber lasers are shown in fig. 6.
