Isotopically Selective Multiphoton Dissociation of UF6in Static Gas Cell tit −35°C

Enhancement of Stokes conversion by diode-laser injection in a para-H(2) Raman laser

The injection effect of weak Stokes seed radiation is demonstrated in a para-H(2) Raman laser. Injected radiation from a PbSnTe diode laser as low as several microwatts resulted in an enhancement of 4 orders of magnitude in the output Stokes energy and a reduction in the pumping threshold energy of 22%. Characteristics of the injection are investigated as functions of the pumping energy, the Stokes seed frequency, and the polarization.

Accurate extraction of reaction probabilities in IR multiphoton dissociation by a focused Gaussian beam: an improved analytical method

An improved analytical method has been developed to extract the dissociation probability from the raw data in infrared multiphoton dissociation with a Gaussian-profile beam using a focused irradiation geometry. The conventional analytical method based on the power-law model is shown to overestimate the dissociation yield by as much as 60% compared with that predicted by the newly developed analytical method based on the cumulative log-normal distribution model. The obtained analytical solution is well fitted bysimple algebraic expressions, which enable us to analyze the experimental data quickly and accurately without tedious iteration procedures.
