Laser diodes

Description

The University of Birmingham invites tenders for supply of full octave spanning frequency comb. The frequency comb provides inputs for 698-nm, 578-nm, 775-nm, and 1040-nm light. The comb offers a high absolute frequency stability as described below. The comb system is provided with a suite of lasers required for laser-cooling of ytterbium atoms. The overall system includes all necessary driving and locking electronics. The University of Birmingham invites tenders for supply of full octave spanning frequency comb.
