High frequency stability semiconductor laser sources at 760 nm wavelength
Original language description
Measurement with nanometer resolution is required for the next advance in nanotechnology. Especially the non contacting methods of measurement are very.promising. We present the set-up of the laser interferometer with nanometer resolution. We developed three types of laser sources especially for using in laser interferometry and absolute laser interferometry. The standard He-Ne laser source for conventional laser interferometry techniques can be replaced by one of these tree types of laser sources. We used Vertical Surface Emitting Laser (VCSEL) and Distributed Feed-Back (DFB) laser diodes to design these laser sources. For these laser diodes we developed several methods to improvement their wavelength stability and tunability by fiber Bragg gratings (FBGs). We developed simulation method to calculation of arbitrary fiber grating (apodized, chirp etc.) with high precision by combination of methods based on layered dielectric media (LDM) and transfer matrix.
