CHEMICAL DETECTION AND LASER WAVELENGTH STABILIZATION EMPLOYING SPECTROSCOPIC ABSORPTION VIA LASER COMPLIANCE VOLTAGE SENSING

摘要

Systems and methods are disclosed that provide a direct indication of the presence and concentration of an analyte within the external cavity of a laser device that employ the compliance voltage across the laser device. The systems can provide stabilization of the laser wavelength. The systems and methods can obviate the need for an external optical detector, an external gas cell, or other sensing region and reduce the complexity and size of the sensing configuration.
