AI Technical Summary
Technical Problem
Conventional pulse light generation devices struggle with controlling the wavelength of multi-solitonized pulse light, leading to potential crosstalk in applications like two-photon microscopes.
Method used
A pulse light generation device that broadens the spectrum of seed light using soliton self-frequency shift, modulates the wavelength, and amplifies dispersion waves to establish a one-to-one correspondence between soliton and dispersion wave wavelengths, allowing precise control through intensity modulation.
Benefits of technology
Generates pulse light with high wavelength controllability, reducing crosstalk and enhancing the performance of devices like two-photon microscopes.

Abstract
This pulsed light generation device (1A) comprises: an oscillator (oscillation unit) (2) that oscillates pulsed light as seed light (L0); a fiber amplifier (band widening unit) (3) that widens the spectrum of the seed light (L0) oscillated by the oscillator (2); a soliton shift fiber (wavelength modulation unit) (6) that modulates, using a soliton self-frequency shift, the wavelength of the seed light (L0), the spectrum of which has been widened by the fiber amplifier (3), the soliton shift fiber (wavelength modulation unit) (6) generating a soliton wave (LS) and a dispersion wave (LD) caused by the seed light (L0); and a fiber amplifier (dispersion wave amplification unit) (9) that amplifies the dispersion wave (LD) generated by the soliton shift fiber (6).
