    Abstract: PROBLEM TO BE SOLVED: To provide a means suitable for coupling a multimode optical fiber with a low NA(numerical aperture) with a laser diode. SOLUTION: Before butt-coupling the output of the laser diode with an optical fiber, a small diameter multimode optical fiber having a low numerical aperture (i.e., 0.1) is used as a microlens to collimate the output emissions of the laser diode. The optical fiber used as the microlens is selected so that its diameter is roughly equal to the diameter of the fiber to be coupled with the laser diode. The collimation is performed in the high NA direction of the output of the laser diode. The output of a bundle of butt-coupled optical fibers can be used for pumping a laser system.

    Abstract: A Fourier Transform Raman Spectrometer system includes a folded V laser cavity. A first leg of the folded V laser cavity is defined by a highly reflective end mirror and a dichroic fold mirror and a second leg of the folded V laser cavity is defined by the fold mirror and an output coupler. A solid-state laser gain medium is disposed in the first leg of the folded V laser cavity and is pumped by a pump source aligned with the optical path of the first leg of the laser cavity and radiating through the fold mirror. The fold mirror is highly transmissive at the wavelength of pump radiation from the pump source and highly reflective at the laser output wavelength. An output beam from the laser is passed through a tuneable filter comprising an acousto-optic device and is directed at a sample to be analyzed. Light reflected from the sample is directed to a Raman Spectrometer for analysis.

    Abstract: A small diameter multimode optical fiber (26) with a low numerical aperture (i.e., 0.1) is used as a microlens to collimate the output emissions of a laser diode emitters (12,14 and 16) before butt coupling the output of the laser diode array to an optical fiber bundle (24). The optical fiber used as the microlens is chosen such that its diameter roughly equals the diameter of the fibers (18,20,22) to be coupled to the laser diode emitters (12,14,16). The collimation is performed in the high NA direction of the output of the laser diode. The output of a bundle of butt coupled optical fibers may be used to pump a laser system.
