We use amplitude-modulation techniques to investigate the response of a multimode dye laser when its pump intensity is sinusoidally amplitude modulated. A theoretical model is presented based on a Floquet analysis to obtain the stationary-state first-harmonic response of the population inversion and that of the laser intensity as a function of modulation frequency. We perform experiments in multimode continuous-wave dye lasers to demonstrate the validity of this theory in describing the behavior of multimode lasers operating near the lasing threshold.We use amplitude-modulation techniques to investigate the response of a multimode dye laser when its pump intensity is sinusoidally amplitude modulated.

Investigation of loading of pulsed and continuous-wave optical dipole force traps

We have investigated the behavior of an optical dipole force trap realized using a mode-locked Nd:YAG laser and have compared performance to a continuous-wave (cw) trap built using the same laser but running in a cw mode. The traps are used to confine ultracold $^{85}\text{R}\text{b}$ atoms which are loaded from a magneto-optical trap (MOT). In most respects, the two traps behave similarly over a wide range of laser parameters provided that the average potential well depth is the same; however, there is a notable difference in the dipole trap loading efficiency dependence on the detuning of the MOT trap laser frequency during the loading stage.We have investigated the behavior of an optical dipole force trap realized using a mode-locked Nd:YAG laser and have compared performance to a continuous-wave (cw) trap built using the same laser but running in a cw mode.
