This proposal seeks funding to complete an engineering prototype of a newly developed, low cost, auto-locked diode laser system. This narrow line width laser system can be frequency stabilized with reference to atomic or molecular spectral lines with out the need for human intervention. Laboratory prototypes of this system have met desired performance specifications in tests with commercial gravimeters. Integration of these laser systems into gravimeters manufactured by the industrial partner can substantially reduce the cost of these sensors, which are used in an array of geophysical applications such as oil and mineral prospecting, borehole mapping, correction of tidal charts and seismic monitoring.

该提案寻求资金，以完成新开发的低成本自动锁定二极管激光系统的工程原型。这种窄线宽激光系统可以参考原子或分子光谱线进行频率稳定，而不需要人为干预。该系统的实验室原型在商业重力仪的测试中达到了预期的性能规格。 将这些激光系统集成到工业合作伙伴制造的重力仪中可以大幅降低这些传感器的成本，这些传感器用于一系列地球物理应用，例如石油和矿产勘探、钻孔绘图、潮汐图校正和地震监测。
