Spontaneous Generation of Vortex Array Beams from a Thin-Slice Solid-State Laser with Wide-Aperture Laser-Diode Pumping
Kenju Otsuka, Shu-Chun Chu
We studied complex lasing pattern formations in a thin-slice solid-state laser with wide-aperture laser-diode end-pumping. Radial and rectangular vortex arrays were found to be for…

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…

Non-stationary Characteristics of the instability in a Single-mode Laser with Fiber Feedback
Tsung-Hsun Yang, Tsong-Hsin Lim, Jyh-Long Chern +1
Chaotic bursts are observed in a single-mode microchip Nd:YVO laser with fiber feedback. The physical characteristic of the instability is a random switching between two differ…
