Low-cost Custom Fabrication and Mode-locked Operation of an All-normal-dispersion Femtosecond Fiber Laser for Multiphoton Microscopy
Published on: November 22, 2019
Abstract:
A simple single-frequency He-Ne laser is described in which the cavity ength is designed to be of high stability. The components are precision-made by standard workshop methods so that the laser requires no adjustments after assembly and the reflectors and capillary plasma tube are readily replaceable. Over a period of hours, frequency stability was within 0.01 ppm, with the krypton-86 primary wavelength standard as reference.
