Abstract

In this paper, we present an overview of different laser resonator configurations leading to smooth single transverse mode of large cross sectional area. Particular attention is given to Cassegranian resonators in which one of the mirror has a radially varying reflectivity profile. Experimental results obtained with TE-CO₂ lasers are discussed. It is shown that graded reflectivity mirrors are particularly well suited to frequency stable laser emitters in coherent lidar applications.
