Since the 1960s, lamp-pumped atomic magnetometers have been essential instruments in magnetic prospecting.
Renowned for their high precision and sensitivity, these magnetometers offer a wide measurement range, fast response time, and excellent stability. They are widely used across multiple fields, including:

• Mineral Resource Exploration: Locating magnetic minerals such as iron, nickel, and titanium ores, as well as non-ferrous deposits like gold, copper, and lithium.

• Oil and Gas Exploration: Identifying magnetic structures associated with hydrocarbon reserves.

• Engineering Geology: Investigating subsurface structures and assessing geological hazards.

• Environmental Geology: Monitoring underground pollution and mapping waste distribution.

• Scientific Research: Supporting a wide range of geophysical and space science studies.

 

Our Breakthrough: Miniature Laser-Pumped Magnetometer

​

We have developed a next-generation miniature laser-pumped magnetometer, optimized for high-resolution scalar magnetic field measurements in complex geomagnetic environments.

​

This new design retains the sensitivity, measurement range, and bandwidth of traditional optically pumped magnetometers, ensuring full compatibility with existing applications.

​

The core advancement lies in replacing the traditional cesium lamp with a VCSEL (Vertical-Cavity Surface-Emitting Laser) semiconductor diode. This shift delivers multiple benefits:

​

• Significantly reduced power consumption

• Smaller size and lighter weight

• Enhanced overall performance and stability​

 

These improvements allow seamless integration into compact platforms such as small UAVs and autonomous underwater vehicles, greatly expanding the range of field applications.
