PTK Femtosecond comb system / Femtosekundové hřebeny

SUBJECT-MATTER DESCRIPTION

The subject of the tender is a femtosecond comb system that performs the following tasks: a) The 171Yb+ optical clock clockwork (for both E2 and E3 transitions, each of the fundamental wavelengths 871 nm, 934 nm can be used as reference and the system shall generate a high quality 10 MHz signal derived from the optical frequency). b) Accurate determination of the ratio of the optical frequencies of the E2/E3 clock lasers. c) Frequency transfer (accuracy and stability) to another optical wavelength - single frequency laser 1542.14 nm. This laser and its comb stabilization is optionally included. d) Frequency measurement (optional stabilization) of the fundamental (740 nm) frequency of the cooling laser. In case of stabilization, the offset of the comb mode should be adjustable. e) Measurement of the frequency of the wavelength standards – 633 nm, 1064 nm and 1542 nm, and optionally other wavelengths. (f) Provision of fs comb radiation for length/spectroscopic measurements.
