Low-frequency amplitude noise in femtosecond laser supercontinuum generation originates from amplified input laser noise. This amplification factor depends on supercontinuum wavelength and input pulse energy and duration.

Area of Science:

* Physics and Optics
* Nonlinear Optics
* Laser Technology

Background:

* Supercontinuum generation using femtosecond laser pulses in microstructure fibers is a key technology.
* Output pulse trains can exhibit significant low-frequency amplitude noise (<1 MHz).
* The origin and characteristics of this noise are not fully understood.

Purpose of the Study:

* To identify the source of low-frequency amplitude noise in femtosecond laser supercontinuum generation.
* To quantify the noise amplification factor and its dependencies.
* To differentiate this noise from broadband white-noise components.

Main Methods:

* Experimental measurements of amplitude noise on input and output pulse trains.
* Numerical simulations of supercontinuum generation dynamics.

* Analysis of noise amplification dependence on wavelength, input pulse energy, and duration.

Main Results:

* Low-frequency amplitude noise is an amplified version of input laser pulse train noise.
* Noise amplification factor is quantified and shown to depend on supercontinuum wavelength.
* Dependence on input pulse energy and duration differs from broadband white-noise amplification.

Conclusions:

* The primary source of low-frequency amplitude noise is the amplification of pre-existing input laser noise.
* Understanding these dependencies is crucial for controlling noise in supercontinuum generation.
* This work distinguishes between different noise mechanisms in nonlinear fiber optics.
