This paper reexamines a 60 year old mystery of spiking behavior in rubylasers with a cw 532 nm pump, paying special attention to mode matching betweenthe pump and lasing beam within a ruby crystal placed in a semi-confocal lasercavity. Periodic spiking oscillations were observed in a limited pump powerregime, where spikes obeying the generic asymmetric hyperbolic functionappeared at a repetition rate around 50 kHz and with a 130-150 ns width and0.1-0.6 microjoule energy depending on the pump power. The physics of thespiking behavior based on Kleinman's mechanical approach and a plausibleinterpretation for the periodic spiking oscillation in terms of self-inducedmode matching between the pump and laser beams through the self-inducedKerr-lens effect are addressed. The statistical nature inherent to spiking andthe associated self-organized critical behavior in quasi-periodic spikingoscillations as well as chaotic states occurring outside the periodic spikingregime are also explored from a nonlinear dynamics point of view.
