We developed a stable, all-fiber laser source producing ultra-short, two-cycle pulses. This tunable fiber laser system offers precise control over supercontinuum generation for advanced optical applications.

Area of Science:

  • Fiber optics
  • Nonlinear optics
  • Ultrafast lasers

Background:

  • Generating ultrashort optical pulses is crucial for many scientific fields.
  • Existing methods often lack stability or tunability.
  • Highly nonlinear fibers (HNFs) offer potential for novel pulse generation.

Purpose of the Study:

  • To demonstrate a stable, all-fiber turnkey source for 2-cycle pulses.
  • To explore the generation of tunable supercontinua using HNFs.
  • To precisely control spectral characteristics of generated pulses.

Main Methods:

  • Utilized Taylor-cut highly nonlinear germano-silica bulk fibers (HNFs).
  • Employed 1.55 micrometer pump pulses with controlled phase.
  • Performed parameter-free simulations of nonlinear pulse propagation, including higher-order dispersion and Raman effects.
