We have studied filamentation and supercontinuum generation by focusing the intense femtosecond laser pulses into an absorptive medium ( Cu SO 4 aqueous solution). A broad spectrum from 350 to 950 nm with a flat plateau spanning approximately from 450 to 700 nm with a flatness of 9% is obtained without any additional filters. The results indicate that the absorptive medium not only suppresses the strong surplus femtosecond laser signal but also flattens the supercontinuum spectrum efficiently.
