Infrared lasers exist that can produce a nearly monochromatic (single-frequency) output with wavelength λ = 800 nm.

(a) Calculate the frequency of this laser output in Hz.

(b) Techniques have been developed to chop the output of such a laser into pulses lasting for times as short as a few femtoseconds (1 fs = 1 femtosecond = 1015s). If the output of the infrared laser of (a) is chopped to produce a single 20 femtosecond long pulse, how many oscillations will this wave packet contain?
