Summary

• What is new: Development of a fiber-optic nonlinear wavelength converter (FNWC) that enables ultrafast laser technology to produce tunable optical pulses suitable for femtosecond biophotonics.
• Why this is important: The difficulty of accessing ultrafast laser technology for applications requiring tunable central wavelength, pulse repetition rate, and pulse width in the picosecond-femtosecond regime.
• What the research proposes: A reliable accessory for femtosecond ytterbium fiber chirped pulse amplifiers, FNWC, that allows for adaptive, fiber-delivered pulses with tunable parameters, suitable for femtosecond biophotonics.
• Results: The FNWC enables the delivery of ~20 nJ pulses with central wavelengths from 950-1150 nm, repetition rates from 1-10 MHz, and pulse widths from 40-400 fs, with a stability of 2000 hours.

Technical Details

Technological frameworks used: Use of FNWC in conjunction with femtosecond ytterbium fiber chirped pulse amplifiers for pulse delivery.

Models used: Integration with modern machine learning and large-scale fluorescence lifetime imaging microscopy for intravital imaging.

Data used: nan
