Passively stabilized internal co-incident laser (PASSILVELY STABILIZED INTRACAVITY DOUBLING LASER)

摘要

The diode-pumped laser is a wavelength converted using an internal cavity nonlinear photonic crystal 8 and the wavelength converted output 9 is passively stabilized by a short cavity using a non-polarized laser. End pumping limits a number of transverse cavity modes, and the internal cavity etalon effect can be achieved by an additional coating 5 'deposited on a laser or non-linear crystal. The wavelength converted output is enhanced by minimizing the inverse transformation in the linear cavity or reinforced by folding the cavity through the non-linear or slanted surface of the laser crystal (1).
