Abstract

An all-solid-state Kerr-lens mode-locked Cr₄₊:Mg₂SiO₄ (Cr:forsterite, Cr:F) laser operating at a central wavelength of 1.25 mum has been constructed and characterized for frequency metrology applications. The pulse repetition rate of the laser was phase-locked to an H-maser-referenced oscillator. The laser´s operational wavelength range has been extended from 1 to 1.7 mum by means of a spectral broadening of unamplified 40 fs pulses in a highly nonlinear optical fiber. A feasibility to employ the resulting comb of equidistant optical frequencies for frequency measurements in the infrared has been demonstrated
