A highly efficient frequency doubler is developed for femtosecond pulses. Design aspects of the device are discussed. Doubling bandwidth calculations have shown, that with one millimeter long crystals pulses as short as 10 fs can be frequency doubled. Experimental results testing the doubler with 300 fs, 496 nm pulses are presented showing no spectral narrowing.
