    摘要: Systems and methods for automated laser microdissection are disclosed. In one variation, targeted biological material is manually or automatically selected and a transfer film is placed in juxtaposition to the location of an interior of a cut path. In another variation, a sample of biological material is mounted onto a polymer membrane which is then placed onto a substrate. Targeted biological material is manually or automatically selected and a transfer film is placed in juxtaposition with the targeted biological material on the side of the biological material. In yet another variation, a sample of biological material is mounted onto a polymer membrane which is then inverted onto a substrate. Targeted biological material is manually or automatically selected and a transfer film is placed in juxtaposition with the targeted biological material on the side of the polymer membrane. Then, an UV laser cuts along a cut path around the targeted portions of biological material in a closed cut path or a substantially closed cut path defining an interior and an exterior portion of the tissue sample. In a substantially closed cut path, bridges are left spanning the interior of the cut path and the exterior of the cut path. An IR laser activates at least a portion of the transfer film such that the transfer film in the vicinity of targeted portion adheres to the biological material interior to the cut path. The transfer film is then removed separating the targeted portions of biological material which are adhered to the transfer film from the remaining portion of the tissue sample.

    摘要: A laser capture microdissection lift-off substrate comprising a transparent thermoplastic film is incorporated into substrate which may take the form of a cap or other structure associated with an analysis vessel or which may be used with a holder or other element of a LCM tissue sample transfer apparatus. The thermoplastic lift-off substrate film is held in a fixed position on the substrate which may be relative to a feature of a biological analysis vessel. The film may be affixed to a substrate which is a structure which goes into the vessel such that the sample is held in a fixed position relative to an observation port on the vessel.

    摘要: A miniaturized Q-switch is added to the resonant cavity of a compact laser diode pumped solid state laser to produce short high peak power pulses. Q-switching the compact diode pumped solid state lasers takes advantage of the relatively high gain and short cavity length to provide a desirable combination of pulsewidth and pulse energy. Nd:YAG or Nd:YLF are useful solid state laser materials for Q-switching, or other longer lifetime rare earth ions such as erbium or holmium for greater energy storage. The Q-switch is formed of a material such as TeO.sub.2, SF.sub.10, or LiNbO.sub.3 with an acoustooptic figure of merit substantially greater than fused silica. Pulsewidths of 10-50 ns are achieved at pulse energies of 10-20 microjoules. TEMOO output is easily produced by the compact laser pumped solid state resonator. Applications include materials processing, link blowing in semiconductor memories, marking and scribing, and optical time domain reflectometry.

    摘要: A KTP crystal in a nonlinear optical device is heated to and operated at a temperature of at least 50.degree. C. and less than 350.degree. C., and more preferably about 90.degree. C. to about 200.degree. C., and most preferably to about 100.degree. C. to about 125.degree. C., to reduce drift and damage. The KTP crystal is placed in an oven or other heating device, which may be regulated or unregulated. The KTP may be cut at the room temperature phase matching angle and angle tuned for operation at the higher temperature, or the KTP may be cut at the correct angle for phase matching at the operating temperature.
