Abstract :
Simultaneous single-frequency oscillations on different transitions have been observed experimentally in a laser-diode-pumped microchip LiNdP4O12 laser. The peculiar modal input-output characteristics and the antiphase relaxation oscillation dynamics have been reproduced theoretically using rate equations, including the strong spatial localization of population inversions, cross saturation, and resonant reabsorption loss in an unpumped region brought about by the inherent high Nd concentrations
