Engineering prototype development of an auto-locking laser system for industrial gravimeters with spectroscopic applications

这项提案寻求资金，以完成一种新开发的低成本自动锁定半导体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谱线进行频率稳定，而不需要人工干预。该系统的实验室样机在商业重力仪的测试中达到了预期的性能指标。将这些激光系统集成到工业合作伙伴制造的重力仪中，可以大大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，如石油和矿产勘探、钻孔测绘、潮汐图校正和地震监测。 工程原型将被开发为在633 nm和780 nm的波长下运行。633纳米的原型将迎合与工业合作伙伴制造的重力仪相关的利基市场。由于这些激光系统可以在使用二极管激光器可访问的波长范围内开发，780 nm的原型将展示出满足与精密光谱、计量和实验室教学套件相关的更大市场的潜力。 自动锁定激光系统的一个版本也将被开发为基于半导体激光的激光雷达发射器。该系统的未来工程原型可以集成到用于大气研究和污染监测的激光雷达系统中。

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. Engineering prototypes will be developed to operate at wavelengths of 633 nm and 780 nm. The prototypes at 633 nm will cater to a niche market associated with gravimeters manufactured by the industrial partner. Since these laser systems can be developed over the range of wavelengths accessible using diode lasers, prototypes at 780 nm will demonstrate the potential to address a larger market associated with precision spectroscopy, metrology and laboratory instructional kits. A version of the auto-locked laser system will also be developed as a diode laser-based lidar transmitter. Future engineering prototypes of this system can be integrated into lidar systems used for atmospheric studies and pollution monitoring.
