An optical spectroscopy apparatus determines the concentration of analyte in a specimen that utilizes a single radiation source which is hybrid laser comprising a semiconductor pump laser and small-cavity rare earth fiber laser where laser cavities of both lasers are butt coupled or otherwise optically coupled to form a plurality of laser cavities that produce a plurality of emission wavelengths, one which may be the pump laser emission wavelength at the output of the fiber laser thereby forming a multi-wavelength combined output where the wavelengths substantially match distinguishing spectral characteristic features along at least a portion of a characteristic optical spectrum of the analyte under examination.
An optical spectroscopy apparatus for determining the concentration of analyte in a specimen that utilizes a radiation source comprising at least one combination of a semiconductor pump laser and small-cavity fiber laser where laser cavities of both lasers are butt coupled to provide a plurality of laser cavities that produce a plurality of emission wavelengths at a same output of the butt coupled laser that are designed to substantially match distinguishing spectral characteristic features along at least a portion of an characteristic optical spectrum of the analyte under determination.
