    摘要: A wavelength-agile laser transmitter apparatus and method are provided. The apparatus comprises a pump laser that is configured to output a pump beam at a first (pump) wavelength and an optical parametric oscillator. The optical parametric oscillator comprises a cavity that contains several optical components including a non-linear optical medium, a first, second and third optical elements, and a narrow line width filter. The non-linear optical medium is configured to convert light at the first wavelength to light at a second (signal) wavelength and a third (idler) wavelength that are each longer than the first wavelength. Light at the second and third wavelengths is allowed to partially resonate in the optical parametric oscillator, and the output beam of the apparatus corresponds to light at the third wavelength.

    摘要: The present invention relates to a method and to an arrangement for the frequency conversion of coherent optical radiation with adjustable wavelength by way of a two-stage nonlinear optical process. In the method and the arrangement, a frequency doubling is carried out in a first nonlinear optical crystal (301, 302) and a sum frequency generation or a frequency doubling is carried out in a second nonlinear optical crystal (401, 402) which is connected downstream. A positively birefringent crystal, in which the frequency doubling is carried out during a phase matching of type I from the extraordinary wave of the output frequency according to the scheme , is used as the first nonlinear optical crystal (301, 302). The second nonlinear optical crystal (401, 402) is chosen such that phase matching is made possible by rotating the crystal in the same spatial plane in which the first crystal (301, 302) must also be rotated during a phase matching. The method and the arrangement can be used to realize an extremely compact conversion arrangement with high conversion efficiency, which conversion arrangement can be used for a broad tunable wavelength range of the input radiation.

    摘要: An apparatus (10a) for scanning a light beam (16) through a crystal arrangement (22) that has a first frame member (28), a first support member (24) to support a first optical element (18) in the first frame member (28) and a drive mechanism (32) to rotate the first support member (24). The first support member (24) is rotatably mounted in the first frame member (28). The first optical element (18) is arranged to receive the light beam (16). The first optical element (18) is supported by the first support member (24) so that the first optical element (18) is rotatable with the first support member (24). The first optical element (24) is tiltable about a diametral line of the first optical element (18), relative to the axis of the light beam (16) to be scanned through the crystal arrangement (22).A frequency conversion apparatus (50) provides a first crystal set (52) and a second crystal set (54). Each of the first and second crystal sets (52, 54) has at least one non-linear optical crystal. The first crystal set (52) receives a beam (16) of coherent radiation that passes through the first crystal set (52). The second crystal set (54) receives the beam (16) after it passes through the first crystal set (52), and the beam (16) then passes through the second crystal set (54). One of the first and second crystal sets (52, 54) is aligned for frequency conversion of the beam (16) in the cold state of that crystal set and the other one of the first and second crystal sets (52, 54) is aligned for frequency conversion of the beam (16) in the warm steady state of that other crystal set.
