A Yb:KYW Laser Pumped by a Powerful Single-Mode Tapered Diode Laser
A powerful single-mode distributed Bragg reflector diode laser with a low-noise power supply is developed. The output characteristics of the tapered diode laser are investigated. Using such a laser as a pumping source, the free running mode of a Yb:KYW laser is achieved and investigated. It is shown that a compact precision femtosecond frequency synthesizer based on Yb:KYW laser pumped by a similar type of diode laser can be created.
