“…It has been set to 7.4 × 10 −14 Hz −1/2 at 0.18 mHz, which poses a serious challenge due to the very low frequency of interest. For comparison, the requirements of other cavities working in the low frequency range, e.g., the LRI [27,28], LISA [29] and the next generation of gravity field missions [30,31], are in the 10 −10 Hz −1/2 levels at 0.18 mHz, i.e., 1000 times less demanding.…”

BOOST (BOOst Symmetry Test) is a proposed space mission to search for Lorentz invariance violations and aims to improve the Kennedy-Thorndike parameter constraint by two orders of magnitude. The mission consists of comparing two optical frequency references of different nature, an optical cavity and a hyperfine transition in molecular iodine, in a low Earth orbit. Naturally, the stability of the frequency references at the orbit period of 5400 s (f =0.18 mHz) is essential for the mission success. Here we present our experimental efforts to achieve the required fractional frequency stability of 7.4 × 10 −14 Hz −1/2 at 0.18 mHz (in units of the square root of the power spectral density), using a high-finesse optical cavity. We have demonstrated a frequency stability of (9 ± 3) × 10 −14 Hz −1/2 at 0.18 mHz, which corresponds to an Allan deviation of 10 −14 at 5400 s. A thorough noise source breakdown is presented, which allows us to identify the critical aspects to consider for a future space-qualified optical cavity for BOOST. The major noise contributor at sub-milli-Hertz frequency was related to intensity fluctuations, followed by thermal noise and beam pointing. Other noise sources had a negligible effect on the frequency stability, including temperature fluctuations, which were strongly attenuated by a five-layer thermal shield.

“…The MARLI laser requires a low power single frequency laser to seed the laser's ring oscillator in order to maintain a stable single frequency emission. Our approach uses a micro-non-planar ring oscillator (µNPRO) that is being developing for the Laser Interferometer Space Antenna (LISA) mission [57]. The µNPRO allows higher power and narrower, and much more stable linewidth than a diode seed laser in a small, efficient package.…”

Design of a direct-detection wind and aerosol lidar for mars orbit

The present knowledge of the Mars atmosphere is greatly limited by a lack of global measurements of winds and aerosols. Hence, measurements of height-resolved wind and aerosol profiles are a priority for new Mars orbiting missions. We have designed a direct-detection lidar (MARLI) to provide global measurements of dust, winds and water ice profiles from Mars orbit. From a 400-km polar orbit, the instrument is designed to provide wind and backscatter measurements with a vertical resolution of 2 km and with resolution of 2° in latitude along track. The instrument uses a single-frequency, seeded Nd:YAG laser that emits 4 mJ pulses at 1064 nm at a 250 Hz pulse rate. The receiver utilizes a 50-cm diameter telescope and a doubleedge Fabry-Pérot etalon as a frequency discriminator to measure the Doppler shift of the aerosol-backscatter profiles. The receiver also includes a polarization-sensitive channel to detect the cross-polarized backscatter profiles from water ice. The receiver uses a sensitive 4 × 4 pixel HgCdTe avalanche photodiode array as a detector for all signals. Here we describe the measurement concept, instrument design, and calculate its performance for several cases of Mars atmospheric conditions. The calculations show that under a range of atmospheric conditions MARLI is capable of measuring wind speed profiles with random error of 2-4 m/s within the first three scale heights, enabling vertically resolved mapping of transport processes in this important region of the atmosphere.

“…It is not until Freitag [3] proposed the curved Nd: YAG crystal design in 1995 that the power of Nd:YAG NPRO lasers were increased to about 2 W. Nd:YAG NPRO lasers have very low power noise [4], frequency noise [5] and good spatial beam profile [6]. With these advantages Nd:YAG NPRO lasers can be used in many precision measurement fields such as gravitational wave detection, like LIGO [7], GEO600 [8], and LISA [9]. Nd:YAG NPRO lasers can also be frequency doubled to 532 nm, and used in molecular Iodine frequency stabilization, which is used for length standard traceability [10] [11].…”

Monolithic Nd: YAG lasers pumped by laser diodes have been widely used in precision measurement fields due to its low frequency noise and intensity noise. Previously, people found that the intensity noise of the pump laser would affect the frequency noise of the Nd: YAG lasers, but the cause has not been well explained so far. In this paper, we propose that this effect is thermally induced. The experimental results agreed well with the theoretical model predictions in up to 60 kHz frequency range. The finding can provide ideas for further reducing the frequency noise of Nd: YAG lasers. We get about 300 Hz linewidth in NPRO laser pumped by single laser diode.
