# Collapse events of two-color optical beams

## TL;DR

This paper investigates the collapse events of two-color optical beams due to self-focusing, analyzing how combined power and power ratios influence collapse in various beam configurations.

## Contribution

It introduces a model for collapse events in co-propagating two-color beams, highlighting the dependence on combined critical power and power ratios.

## Key findings

- Collapse depends on combined critical power for different beam types
- Power ratio influences collapse events
- Collapse behavior varies with beam configuration

## Abstract

In this work, we study optical self-focusing that leads to collapse events for the time-independent model of co-propagating beams with different wavelengths. We show that collapse events depend on the combined critical power of two beams for both fundamental, vortex and mixed configurations as well as on the ratio of their individual powers.
