Claim 14:
15. A method for generating very high-rate laser pulses, the method comprising:
generating a series of source pulses of femtosecond or picosecond duration by an oscillator having a first repetition frequency higher than or equal to 800 megahertz;
optically amplifying the series of source pulses to a second repetition frequency equal to or multiple of the first repetition frequency, the multiple being a natural integer number higher than or equal to two to generate a series of very high-rate laser pulses;
spatially splitting the source laser beam into a first pulse beam at the first repetition frequency and a second pulse beam at the first repetition frequency;
inducing an optical delay equal to a half-period of the first repetition frequency on the second pulse beam to generate a second pulse beam delayed by a half-period; and
recombining the first beam and the second beam, delayed by a half-period, and formation of a first recombined beam in which the pulses are rated at the second repetition frequency equal to twice the first repetition frequency.
