    Hydrogenic impurity bound polaron in a quantum dot quantum well structure

    A variational approach is used within the framework of effective mass approximation to study the binding energy of the hydrogenic impurity in a spherical quantum dot quantum well (QDQW) structure. The electron...

    Continuous-wave and passively Q-switched Nd:LYSO lasers

    Continuous-wave (CW) and passively Q-switched performance of a Nd-doped oyorthosilicate mixing crystal, (Nd0.005Lu0.4975Y0.4975)2SiO5 (Nd:LYSO), were reported. As a result, new dual-wavelength all-solid-state las...

    Exploration of dynamical regimes of irradiated small protonated water clusters

    We explore from a theoretical perspective the dynamical response of small water clusters, (H2O)nH3O+ with n=1,2,3, to a short laser pulse for various frequencies, from infrared (IR) to ultra-violet (UV) and inten...

    Diode-end-pumped passively mode-locked Nd:LuVO4 laser with a semiconductor saturable-absorber mirror

    A diode pumped passively mode-locked Nd:LuVO4 laser with a semiconductor saturable-absorber mirror (SESAM) is demonstrated. The mode-locked pulses have a pulse duration of about 8.8 ps and a repetition rate of 15...

    Polaron effects on excitons in parabolic quantum wells: fractional-dimension variational approach

    Polaron effects on excitons in parabolic quantum wells are studied theoretically by using a variational approach with the so-called fractional dimension model. The numerical results for the exciton binding ...

    Raman Scattering Studies of Optical Phonons in GaAs/AlAs and GaAs/AlxGa1-xAs Superlattices

    It is weL.L. known from the phonon dispersion curves of bulk GaAs and AlAs that though their acoustic branches basically overlap, the optical branches do not. As a consequence, in GaAs/AlAs superlattices the a...
