Quintupling of a laser at telecom wavelength — •Maya Büki, David Röser, and Simon Stellmer — Physikalisches Institut, Universität Bonn, Nussallee 12, 53115 Bonn

The demand for highly accurate frequency standards has lead to the development and improvement of optical clocks. For a broad spectrum of applications, also outside of the laboratory, an improvement of already existing optical clocks is required. The 1S03P0 transition in zinc could form the basis of such a novel optical clock.

The advantage of zinc is that the clock transition at 309.5 nm and the intercombination line 1S03P1 at 307.6 nm can be derived as the fifth harmonic of a laser at telecom C-Band wavelength, which allows transfer of the clock signal via optical fibres.

We report on the development of a frequency quintupled diode laser at 1538 nm using three frequency conversion stages in nonlinear crystals.
