Implication

Theoretical analysis demonstrates identical critical collapse thresholds in hollow-core waveguides and bulk media, suggesting universal power limits across spatial beam profiles.

Key Points

Determine the threshold power for catastrophic self-focusing collapse across different spatial beam profiles in bulk media compared to hollow-core waveguides.
Calculated collapse power thresholds across various spatial beam distributions.
Compared analytical bounds for unconstrained bulk propagation against guided modes in hollow-core waveguides.
The threshold power for collapse in a hollow-core waveguide uniformly equals the lower-bound threshold predicted for a bulk medium across tested spatial profiles.
