US 2025/0012875 A1 · STABILIZATION OF LASER-BASED SENSORS

Abstract

A sensor system structured to measure an environmental property. The device includes a housing with shock absorbers disposed within and a laser cavity network. The laser cavity network includes one or more laser cavity arms, each having a gain chip configured to generate a laser beam and a means for locking a wavelength of the laser beam. The laser cavity network further includes a sensing material disposed within the laser cavity network, configured to accept the one or more laser beams of the one or more laser cavity arms and measure the environmental property in response to the plurality of laser beams. The system further includes a supply and control subsystem communicatively connected to the laser cavity network such that the supply and control subsystem is external to the housing, comprising a laser pumping source.

Dependent claims

A sensor system (100) structured to measure an environmental property, the system (100) comprising:

a. a laser cavity network (120), the laser cavity network (120) comprising:
i. one or more laser cavity arms, each cavity arm comprising:
A. a cavity;
B. a gain chip (122) configured to generate a laser beam;
and
C. a rough tuning filter (123) comprising a birefringent filter operatively coupled to the gain chip (122), configured to coarsely tune the laser beam generated by the gain chip (122) to be within a broad range of wavelengths and maintain a single frequency operation for the laser beam;
and
ii. a sensing material (130) disposed within the laser cavity network (120), configured to accept the one or more laser beams of the one or more laser cavity arms and measure the environmental property in response to the plurality of laser beams;
and
b. a supply and control subsystem (200) operatively coupled to the laser cavity network (120) such that the supply and control subsystem (200) is external to the housing (110), the supply and control subsystem (200) comprising a laser pumping source (210) configured to power each gain chip (122) of the one or more laser cavity arms.
