DFB Laser Source at 760 nm Wavelength for Nanometrology

Popis výsledku v původním jazyce

Measurement with nanometer resolution is required for the next advance in nanotechnology. Especially the noncontacting methods of measurement are very .promising. We present the set-up of the laser interferometer with nanometer resolution. A stabilized laser source with the DFB (Distributed FeedBack) laser diode was developed and its realization was implemented to the laser interferometer. The output of the DFB laser source and the design of optical set-up of the laser interferometer are realized by fiber optics. It will improve repeatability of measuring by reducing the influence of the index of refraction of air. The measurement probe is realized by standard optical fiber with reflection coated optical connector. Due to using of the DFB laser sourceit is possible to measure of the length in incremental or absolute regime. We present possible methods to stabilization and measurement of the tuneability of the wavelength of the DFB laser diode.
