Title: Feasibility of supersonic diode pumped alkali lasers: Model calculations

Abstract

The feasibility of supersonic operation of diode pumped alkali lasers (DPALs) is studied for Cs and K atoms applying model calculations, based on a semi-analytical model previously used for studying static and subsonic flow DPALs. The operation of supersonic lasers is compared with that measured and modeled in subsonic lasers. The maximum power of supersonic Cs and K lasers is found to be higher than that of subsonic lasers with the same resonator and alkali density at the laser inlet by 25% and 70%, respectively. These results indicate that for scaling-up the power of DPALs, supersonic expansion should be considered.

  • The lifetime of Diode-Pumped Alkali Lasers (DPALs) is limited by damage initiated by reaction of the glass envelope of its gain medium with rubidium vapor. Rubidium is absorbed into the glass and the rubidium cations diffuse through the glass structure, breaking bridging Si-O bonds. A damage-resistant thin film was developed enhancing high-optical transmission at natural rubidium resonance input and output laser beam wavelengths of 780 nm and 795 nm, while protecting the optical windows of the gain cell in a DPAL. The methodology developed here can be readily modified for simulation of expected transmission performance at input pump and outputmore » laser wavelengths using different combination of thin film materials in a DPAL. High coupling efficiency of the light through the gas cell was accomplished by matching the air-glass and glass-gas interfaces at the appropriate wavelengths using a dielectric stack of high and low index of refraction materials selected to work at the laser energies and protected from the alkali metal vapor in the gain cell. Thin films as oxides of aluminum, zirconium, tantalum, and silicon were selected allowing the creation of Fabry-Perot optical filters on the optical windows achieving close to 100% laser transmission in a solid optic combination of window and highly reflective mirror. This approach allows for the development of a new whole solid optic laser.« less
  • Here, lasing on the D 1 transition (6 2P 1/2 → 6 2S 1/2) of cesium can be reached in both diode and excimer pumped alkali lasers. The first uses D 2 transition (6 2S 1/2 → 6 2P 3/2) for pumping, whereas the second is pumped by photoexcitation of ground state Cs-Ar collisional pairs and subsequent dissociation of diatomic, electronically-excited CsAr molecules (excimers). Despite lasing on the same D 1 transition, differences in pumping schemes enables chemical pathways and characteristic timescales unique for each system. We investigate unavoidable plasma formation during operation of both systems side by side inmore » Ar/C 2H 6/Cs.« less

  • A comprehensive data set from experiments and model calculations for investigating the behavior of optically pumped supersonic beam lasers is presented. The results for Na/sub 2/ demonstrate the roles of stimulated Raman scattering and one-photon population inversion on the gain for collinear optical pumping of supersonic beam gain media for both circular and slit nozzles. For the wavelengths investigated, Raman gain dominates, and an effective photon conversion of greater than 24% is realized. Lasing both with and without frequency-selective elements is studied. Laser transitions terminating on a large range of vibrational levels of the /ital X/ state are observed. Themore » density-matrix calculations for the gain coefficient include the dynamics of the expansion and the influence of condensation. These results show good qualitative agreement with the experimental data.« less
  • We report the first demonstration of a multimode-diode-pumped gas laser--Rb vapor operating on the 795 nm resonance transition. Peak output of {approx}1 Watt was obtained using a volume-Bragg-grating stabilized pump diode array. The laser's output radiance exceeded the pump radiance by a factor greater than 2000. Power scaling (by pumping with larger diode arrays) is therefore possible.
