Spiking ruby revisited: self-induced periodic spiking oscillations leading to chaotic state in a Cr:Al2O3 laser with cw 532-nm pumping
Kenju Otsuka, Seiichi Sudo
This paper reexamines a 60 year old mystery of spiking behavior in ruby lasers with a cw 532 nm pump, paying special attention to mode matching between the pump and lasing beam wit…
Self-mixing interference in a thin-slice solid-state laser with few feedback photons per observation period
Kenju Otsuka, Seiichi Sudo
Formation of a peculiar lasing pattern leading to a TEM00-like mode accompanied by a nonzero bright outer-ring emission (namely, a modified TEM00 mode) was observed in a 300-μm-thi…
Nonlinear dynamics of a self-mixing thin-slice solid-state laser subjected to Doppler shifted optical feedback
Kenju Otsuka, Seiichi Sudo
Chaotic oscillations of a linearly polarized single longitudinal-mode thin-slice Nd:GdVO4 laser placed in a self-mixing laser Doppler velocity scheme were dynamic characterized in…
Brownian Motion Captured with a Self-Mixing Laser
Kenju Otsuka, Koji Kamikariya, Takayuki Ohtomo +2
We measured the overall motion of Brownian particles suspended in water by a self-mixing thin-slice solid-state laser with extreme optical sensitivity. From the demodulated signal…
