We revisit the model of the laser with feedback and the minimal nonlinearityleading to chaos. Although the model has its origin in laser physics, withpeculiarities related to the CO2 laser, it belongs to the class of the threedimensional paradigmatic nonlinear oscillator models giving chaos. The proposedmodel contains three key nonlinearities, two of which are of the type xy, wherex and y are the fast and slow variables. The third one is of the type xz^2,where z is an intermediate feedback variable. We analytically demonstrate thatit is essential for producing chaos via local or global homoclinicbifurcations. Its electronic implementation in the range of kilo Hertz regionconfirms its potential in describing phenomena evolving on different timescales.
