We report a study of transverse laser cooling on a metastable helium beam using spectrally broadened diode lasers ("white light") to increase its flux. For this purpose, beam profile and atomic flux versus laser power and other parameters have been characterized. We have performed experiments to compare this technique with other transverse cooling methods using monochromatic light. Best results are obtained with a "ziz-zag" configuration using "white light".
