Abstract
The two-photon pumped tri-color highly directional stimulated emission has been achieved based on a set of triplet cuvettes filled with three different multiphoton-active dye solutions. Upon the excitation of a focused 100-fs and 795-nm pulsed laser beam, highly directional and collinear forward stimulated emission beams with three spectral components of 617 nm, 555 nm and 496 nm wavelengths can be simultaneously generated via the mechanism of single-path high stimulated gain. Inside the triple cuvettes, the first dye solution is capable of generating red stimulated emission beam that can pass through the second and third dye solutions without absorptive attenuation, and the green stimulated beam generated from the second dye cuvette can pass through the third dye solution without absorptive loss, the blue stimulated emission beam from the third dye cuvette propagates colinearly with the red and green lasing beams together. Spatial separation of three gain media minimizes reabsorption influence on the forward tri-color output beams, while reabsorption effect allows only the red stimulated emission beam from the first cuvette observable along the backward direction. The spectral, temporal, and spatial properties of tri-color forward output have been presented. The overall lasing efficiency could be up to ~ 10% - ~12% at the pump energy levels of ~ 8 - ~9 µJ. Based on this novel system, multicolor optical data recording has been demonstrated. Multicolor lasing devices have many applications including multiwavelength LIDAR, multicolor-based laser imaging/display, optical data storage/processing, and multicolor holographic technique.
