Laser array for laser scanning microscope for treatment of maculate generation during photodynamic therapy of eye conditions, has mirror designed in reflective manner for wavelength range around fundamental wave length with high threshold

摘要

The array has an end mirror (2), and a wavelength-selective element for a fundamental wave length with a low laser threshold, where multi-mode operation is performed with the fundamental wave length with a high laser threshold. A transmissive wavelength-selective element is arranged within a laser resonator such that spectral selective effect does not exhibit for the fundamental wave length with high laser threshold. Another end mirror is designed in a complete reflective manner for a wavelength range around fundamental wave length with high laser threshold.
