Abstract
This STTR Phase I proposal describes development of a conceptual design for the Miniature Broadband Laser Magnetometer, an advanced high-sensitivity scalar laser magnetometer for next-generation undersea ASW Gradiometer Arrays. The MBLM offers the advanced capability of measuring scalar static and ELF magnetic fields with a sensitivity better than 1.0 pT/ÖHz from 0.001 Hz to 50 Hz. The MBLM design is based on five innovations. The first is a hybrid sensor concept combining low-power nuclear free precession (NFP) for milliHertz signals with an OSP locked-oscillator He4 mode for observation of ELF signals. The second innovation is development of long-relaxation time dual helium isotope cells combining isotopes 3 and 4 in a single cell in collaboration with the University of Texas-Dallas. The third innovation is a fiber coupled laser pump source for pumping both isotopes. The fourth innovation is an omni-directional sense coil for the NFP mode. The fifth innovation is a low-power amplifier/processor chip for the NFP mode. The MBLM offers major advantages for ASW undersea arrays requiring detection and tracking in a gradiometer mode for reduction of geomagnetic noise in the detection band. The feasibility of fabricating a breadboard MBLM in Phase II will be established under this Phase I Project.
