Tantalum pentoxide waveguides for spectral broadening of vertical external cavity surface emitting lasers

Tantalum pentoxide waveguides for spectral broadening of vertical external cavity surface emitting lasers
Tantalum pentoxide waveguides for spectral broadening of vertical external cavity surface emitting lasers
We show the characterisation of spectral broadening in the Tantalum Pentoxide waveguide system as a function of pump wavelength, showing spectra for central pump wavelengths of 0.9 to 1.5 µm (150 fs, 80 MHz). We have achieved octave spanning spectra with approximately 5 mW of laser power coupled in the waveguide at 1 µm pumping wavelength for a linear buried waveguide using a commercial source.

Abstract

We show the characterisation of spectral broadening in the Tantalum Pentoxide waveguide system as a function of pump wavelength, showing spectra for central pump wavelengths of 0.9 to 1.5 µm (150 fs, 80 MHz). We have achieved octave spanning spectra with approximately 5 mW of laser power coupled in the waveguide at 1 µm pumping wavelength for a linear buried waveguide using a commercial source.
