Abstract: A longitudinally pumped. widely tunable, solid state Yb:KYF4 laser was developed with special design for applications to optical frequency metrology and absolute frequency stabilization and for LIDAR measurements in the atmosphere. The KYF crystalline host. combined with efficient diode pumping, allows for wide wavelength tunability at around 1.03 µm,. The novel laser source is being thoroughly characterized in terms of output power and beam quality, amplitude noise, wavelength tunability. and free running frequency stability. The possibility of achieving high quality radiation at 0.51 µm. by frequency doubling in a PPKTP crystal, opens the way to the development a new optical frequency standard locked on the I2 molecule.
