Abstract: PROBLEM TO BE SOLVED: To generate an ultrashort optical pulse having a variable or tunable wavelength from a single light source which emits an ultrashort optical pulse having a fixed wavelength by making a wavelength conversion channel to include an optical parametric generation part for parametric generation of ultrashort pulses different by wavelength. SOLUTION: An ultrashort pulse laser(UPL) 10 to generate an ultrashort optical pulse having a fixed wavelength and at least one wavelength conversion channel(WCC) 121 to 12n are included. The UPL 10 is a mode lock fiber oscillator capable of supplying a picosecond or femtosecond, optical pulse whose typical pulse energy is 10PJ(10×10-12J) to 10NJ(10×10-9J) and typical average power is 0.1 to 100 mW. It is desirable that this fiber oscillator has an all fiber resonator which has not any fiber dispersion control element. Wavelength conversion in WCCs 121 to 12n is performed in an optical waveguide.

Abstract: An ultra-short optical pulse generator has a waveguide with an optical parametric generator section (14) for changing the pulse wavelength. An ultra-short optical pulse generator comprises a wavelength conversion channel (12) for changing the wavelength of optical pulses generated by an ultra-short pulse source (10), the channel having an optical waveguide with an optical parametric generator section (14) for parametric generation of the ultra-short optical pulses of the changed wavelength. An Independent claim is also included for a system comprising the above ultra-short pulse generator for supplying image data to a color picture production apparatus in the form of red, green and blue ultra-short optical pulses. Preferred Features: The ultra-short pulse source is a stationary mode erbium-doped fiber laser, a Ti:sapphire laser, a Cr:forsterite laser, a Cr:LiSaF laser or a Cr:LiSGaF laser.
