Phys. Rev. A 68, 023807 (2003) [9 pages]Capturing a light pulse in a short high-finesse cavityReceived 7 August 2002; published 20 August 2003 We describe a method to couple a light pulse into a cavity with arbitrarily high finesse, with an efficiency that in theory can approach 100% even if the pulse duration is much longer than the round-trip time of the cavity. The spectrum of the pulse is compressed into a single narrow mode in an adiabatic and reversible way. The method uses an input coupler with a variable effective reflectivity which is adapted to match the known temporal shape of the pulse. In addition to a theoretical description of the method, we demonstrate the principle experimentally. © 2003 The American Physical Society URL:
