We demonstrated the first directionally emitting deep sub-wavelength plasmon laser and circuit. The plasmon laser circuit naturally integrates photonic and electronic functionality allowing both efficient electrical modulation and wavelength multiplexing.
Many factors of intracavity perturbation will degrade the output power and beam quality for high power passive Q-switched slab laser. We propose and demonstrate the measurement of output laser beam quality with a side-pump Q-switched zig-zag slab YAG configuration by adopting Hartmann-Shack (H-S) wavefront sensor and Zernike mode reconstruction method. Experiment shows that wavefront properties can...
Many factors of intracavity perturbation will degrade the output power and beam quality for high power passive Q-switched slab laser. In the paper, the experiment test on the output beam quality of a passive Q-switched zig-zag slab Nd:YAG laser has been performed by adopting Hartmann-Shack (H-S) wavefront sensor and Zernike mode reconstruction theory, namely wavefront properties can be fully obtained...
The effect of intracavity aberrated perturbation on output mode properties of a confocal unstable resonator is been experimentally researched by adopting H-S wavefront sensor and Zernike modal wavefront reconstruction. By processing the image of beam facula matrix, wavefront phase properties, Zernike aberrations, PV and RMS error, distribution of circle energy can all be acquired, so beam phase distribution...
The effect of intracavity aberrated perturbation on output mode structure properties of passive confocal unstable resonator is been experimentally researched by adopting Hartmann-Shack (H-S) wavefront sensor and Zernike modal wavefront reconstruction on the basis of numerical simulation. The results show that intracavity tilt perturbation notablely affects outcoupled intensity distribution, and will...
