New tricks in quantum control Conference Paper uri icon


  • Quantum control involving multiple interactions with light of different colors within the same light pulse is analyzed. Experiments on I2have demonstrated up to a 300% enhancement of the multiphoton yield with the appropriately chirped pulse. Such multiphoton control can be the basis of the molecular ` pulse,' capable of inverting the entire electronic ground state population of a molecule to an excited electronic state. This multiphoton quantum control is applied to produce a new class of molecular reporter system for ultrafast measurement of the molecular scale chemical environment, and is used to measure the pH from the fluorescence intensity ratio for positive and negative chirped pulses.
