Novel Diode Pumped Yb:KYF(4) and Yb:YLF(4) Lasers for Optical Frequency Metrology at 1 mu m/0.5 mu m

In this work a longitudinally pumped, widely tunable, solid state Yb:YLF laser was developed with special design for applications to optical frequency metrology, LIDAR measurements in the atmosphere and for absolute frequency stabilization. The YLF crystalline host, combined with efficient diode pumping, allows for wide wavelength tunability at around 1.03 mu m. The novel laser source is being thoroughly characterized in terms of output power, spatial beam quality, single frequency output, and wavelength tunability.
