摘要： According to the present invention, laser performance is improved by appropriately matching the spectral periods of various etalons within the laser cavity. A first embodiment of the invention is a discretely tunable external cavity semiconductor laser where a grid fixing etalon is present in the laser cavity, the grid fixing etalon free spectral range (FSR) is a whole number multiple of the laser cavity FSR, and the grid fixing etalon FSR is a whole number multiple of the chip etalon FSR. A second embodiment of the invention is a fixed wavelength external cavity semiconductor laser where the chip etalon FSR is a whole number multiple of the laser cavity FSR, and a mode suppressing etalon is inserted into the laser cavity such that the mode suppressing etalon FSR is a whole number multiple of the chip etalon FSR. A third embodiment of the invention is a tunable external cavity semiconductor laser where the chip etalon FSR is a whole number multiple of the laser cavity FSR. A fourth embodiment of the invention is a fixed wavelength external cavity semiconductor laser where the chip etalon FSR is a whole number multiple of the laser cavity FSR.

摘要： A laser tuning mechanism which embodies “spectrally dependent spatial filtering” (SDSF) and contemplates two key elements of the tuning mechanism. The first element of the SDSF tuning mechanism is a spectrally dependent beam distortion (i.e. alteration of the amplitude and/or phase profile of the beam) provided by an SDSF tuning element in a laser cavity. The second element of the SDSF tuning mechanism is an intracavity spatial filter which makes the round trip cavity loss a sensitive function of both beam distortion and cavity alignment. Such a laser can be aligned so that a specific beam distortion, which is provided by the SDSF tuning element at a tunable wavelength, is required to obtain minimum round trip cavity loss, thereby providing tunable laser emission. A preferred embodiment of the SDSF tuning mechanism is an external cavity semiconductor laser having a zeroth order acousto-optic tuning element.

摘要： A tunable laser and laser tuning method, based on the interaction of a spectrally dependent beam distortion and a spatial filter within a laser cavity. One embodiment of this laser is an external cavity semiconductor laser in which broad tunability is obtained by the insertion of an acousto-optic tunable filter (AOTF) into the laser cavity such that the intra-cavity laser beam passes through the AOTF in zeroth order.

摘要： Ring-shaped resonant cavities for spectroscopy allow a reduction in optical feedback to the light source, and provide information on the interaction of both s- and p-polarized light with samples. A laser light source is locked to a single cavity mode. An intracavity acousto-optic modulator may be used to couple light into the cavity. The cavity geometry is particularly useful for Cavity Ring-Down Spectroscopy (CRDS).

摘要： A system and method are provided for detecting and quantifying an analyte in vivo. Anti-Stokes Raman scattered radiation emitted from a sample under incident radiation excitation is collected and analyzed. The intensity response is corrected for temperature effects using a Boltzmann correction factor based on the temperature of the sample. The sampled tissue is advantageously the sterile matrix beneath the nail of either a toe or a finger. The incident excitation radiation is projected onto the sterile matrix through the nail, which operates as a window. The present invention may be applied in both the blue/UV and the red/IR regions of the spectrum.
