We report high-resolution measurements of the spatial variation of the optical frequency of an injection-seeded unstable-resonator Q-switched Nd:YAG laser. Images of the second harmonic taken through a molecular-iodine notch filter show frequency variations of as much as 100 MHz (second harmonic) between the center and the edge of the beam.
ABSTRACT
We present a computer model for accurately predicting absorption profiles for molecular iodine cells over the tuning range of frequency-doubled Nd:YAG lasers. The model is compared with experimental data for a number of different cell conditions. This model is intended for use in the design and optimization of absorption filters and for data analysis in applications in which the accuracy of the measurement is related closely to the accuracy with which the filter profile is known.
