Ultrashort-pulse source with controllable wavelength output

摘要: A multiple-wavelength ultrashort-pulse laser system includes a generator producing ultrashort pulses at fixed wavelength, and least one preferably plurality of wavelength-conversion channels. Preferably, fiber is used for generating single-wavelength, pulses. An optical split switch matrix directs the from into wavelength conversion combining disposed downstream channels combines outputs separate single output channel. waveguides formed in ferroelectric substrate by titanium indiffusion (TI) and/or proton exchange (PE) form splitting matrices. Use waveguide allows efficient parametric generation to occur pulse energies achievable with mode-locked source. The can replace different, single-wavelength systems. In its simplest form, be convert more favorable wavelength. For example, generated 1.55 μm erbium converted 1.3 use coherence tomography or wavelengths suitable display, printing machining system.
