Frequency stability limitations of optically pumped lasers due to pump laser instability through dispersion effect
Abstract
Observations of unexpected FIR dispersion phenomena in optically pumped FIR lasers at short (70.5 microns) and long (393 microns) wavelength are reported. This effect has a dramatic influence on the FM conversion factor from the pump laser to the FIR laser, and therefore constitutes an important limitation to the frequency stability of optically pumped laser oscillators. Measurements of IR-FIR transferred Lamb dip in CH3OH and in HCOOH are also reported. The experimental set-up using a saturated, fluorescence-stabilized CO2 reference laser allows precise measurements of pump offset.
