A Powerful Single-Mode Diode Laser with Automated Control as the Source of Pumping of the Ytterbium Laser

A powerful single-mode distributed bragg reflector tapered diode laser with a low-noise automatic power supply has been developed. The output characteristics of the tapered diode laser are investigated. Using such laser as a pumping source, the free running mode of a Yb:KYW laser is obtained and investigated. It is shown that a compact precision femtosecond frequency synthesizer based on a Yb:KYW laser pumped by a diode laser of the similar type can be created.
