# Supercontinuum Generation (SCG)

SCG is the process of dramatically broadening a laser’s spectrum into a wide, continuous bandwidth through nonlinear effects. Unlike traditional χ(3)-based approaches, PINC’s SCG leverages χ(2) nonlinearities. By harnessing χ(2) nonlinearities and advanced dispersion engineering, this enables significantly higher nonlinear efficiency and ultra-low power fceo detection beyond traditional χ(3) approaches.

## Demonstrations

### Multi-octave supercontinuum generation (350 nm–3.3 μm) from a 1 μm pump

### Vis-NIR Comb with fJs of Pump Pulse Energy

With an OPO smaller than a thumbnail, we measured a two-octave comb at ~100 fJ and a three-octave comb at ~400 fJ, spanning spectra from 350 nm to 3 μm.
