摘要： A polarimeter includes a multi-wavelength source for generating electromagnetic waves having at least two different wavelengths, means for separating electromagnetic waves, the electromagnetic waves including electromagnetic waves generated by the multi-wavelength source and electromagnetic waves received from a sample contacted by the electromagnetic waves generated by the multi-wavelength source, a fixed waveplate, wherein the fixed waveplate is configured to convert one polarization state to multiple polarization states that allow for calculations of linear and circular polarization components of the electromagnetic waves, a free space coupler, a beam splitter, and more than one detector. The polarimeter may be used in a method for high-speed measurement of linear and circular polarization components of electromagnetic waves.

摘要： A Q-switched neodymium laser may be operated in the 0.9 &mgr;m [( &lgr;1)] band at relatively high gain levels. The laser uses a birefringent filter which provides selective discrimination for wavelengths near 1 &mgr;m [(&lgr;2)] and prevents parasitic lasing in that wavelength region. The filter includes a specific wavelength dependent crystal quartz wave plate in combination with a linear polarizer. The linear polarizer is placed between two mirrors which define a laser cavity. The wave plate provides exactly 2 full waves of retardation at the desired wavelength &lgr;1 in the 0.9 &mgr;m band, and exactly 1.75 waves of retardation at wavelength &lgr;2 near the center of the 1 &mgr;m band for one pass. A Q-switching device such as a Pockels cell is positioned in the laser cavity to selectively control a pulsed emission at &lgr;1.
