Harmonics-assisted optical phase amplification with a self-mixing thin-slice Nd:GdVO4 laser operating in the self-induced skew cosh Gaussian mode

Kenju Otsuka, Seiichi Sudo

Harmonic-assisted phase amplification was achieved in a 300-micrometer-thick Nd:GdVO4 laser in the self-mixing interference scheme. The key event is the self-induced skew cosh Gaus…
