摘要：A multiple single frequency laser for optical manipulation of molecules ispresented. The multiple single frequency laser comprises generally a multiline lasersource which utilizes one sample of molecular species as a source for the generation ofoptical radiation for manipulating (e.g., cooling) a second, separate sample of the samespecies of molecules. More specifically, the multiple single frequency (MSF) laser

comprises a master controller for controlling the frequency of powerful single frequencypump lasers. Laser beams from the pump lasers excite coherent Raman transitions inmolecules contained in a Raman gain cell. These beams are tuned to specific opticaltransitions in an electronic band of molecules. The molecules contained in the Raman gaincell generate the multiple frequencies needed to manipulate (e.g., cool) the same speciesof molecules in a second, separate sample. The Raman gain cell provides an output beamwhich is presented to a multistage optical amplifier for generating an amplified outputbeam. The amplified output beam is presented to a wavelength selector where unwantedfrequencies are eliminated resulting in a MSF output beam. MSF output beam includesmultiple laser frequencies all of which are synchronously controlled by controlling the

frequency of the pump laser via the controller.
