摘要： Methods and apparatus for decreasing the time required to calculate a ring-down time from sampled ring-down data and/or increasing the accuracy of the calculated ring-down time are provided. The time required to obtain an accurate calculation of a ring-down time is reduced by performing a linear least squares fit using an estimate B1 of the background, then using the results of the fit to estimate the error in B1. The estimated error in B1 is then used to provide an improved estimate of the ring-down time. Alternatively, the time required to accurately calculate a ring-down time is reduced by averaging consecutive data points into “bins” and performing a linear least squares fit to the resulting binned signal. The parameters obtained from the fit to the binned signal are then used to obtain an improved estimate B2 of the background, and the ring-down time is calculated by performing a linear least squares fit using B2. Another method, applicable either by itself or in combination with either of the two preceding methods, is to improve accuracy by providing a low pass filter having a bandwidth related to a shortest expected ring-down time, to filter the ring-down signal before it is sampled.

摘要： A mirror translation assembly having a monolithic mirror support member affixed to a monolithic transducer, where these two members have thin sections that are spaced apart from each other and which are deformable by a transducer affixed to the transducer support member, and where the two support members preferably have substantially the same shape. In this manner, a mirror positioned on the mirror support member can be translated without undesirable tilt, while the high stress regions within the assembly are desirably spaced apart from the bond between the two monolithic members.

摘要： An enclosure for a cavity enhanced optical spectroscopy instrument provides a highly temperature stable environment by positioning the instrument optical cavity away from the enclosure walls and providing a wall mounted heat pump, fan and heat exchanger. The fan causes the gas contained within the enclosure to circulate over the heat exchanger and in a laminar, non-turbulent flow path along interior wall surfaces of the enclosure thereby maintaining the optical cavity in a temperature and vibration stable zone.

摘要： A semiconductor pump laser uses a depolarzer to depolarize the pump light entering the fiber amplifier. The depolarized light source is useful for reducing polarization dependent gain of fiber amplifiers. The pump laser includes one or more semiconductor, coherence-collapsed laser sources emitting polarized pump outputs, and one or more depolarizers disposed to depolarize the polarized pump output from the lasers. One or more fiber outputs are coupled to the one or more depolarizers to receive depolarized pump light. The depolarizer may include an N×M polarization preserving coupler having N inputs and M outputs, N and M being at least 2, an input to the depolarizer at a first coupler input, an output port from the depolarizer at a first coupler output. A polarization-controlling optical path is coupled between a second coupler output and a second coupler input. A polarization of light exiting the N×M coupler through the second coupler output is substantially orthogonal to a polarization of light entering the N×M coupler through the second coupler input.
