Abstract

Stable spatial laser patterns were observed in a high-finesse Fabry–Perot cavity containing up to 2 atm of ${\mathrm{CO}}_2$ and ${\mathrm{O}}_2$. The gases displayed the same sequence of patterns that obey a scaling law of the form $P^{\beta }{p}^2$, where $P$ is the power stored in the cavity, $p$ is the pressure of the gas, and $\beta$ is a material-dependent parameter.
