heal.abstract	A further step in the development of a coaxial-cavity gyrotron operated in the transverse electric TE-31,17 mode at 165 GHz is presented. The gyrotron has been equipped with a quasioptical output system consisting of a Vlasov launcher with a single cut and two mirrors, one with a quasi-elliptic and the other with a nonquadratic phase correcting surface. The radio frequency (RF) power is transmitted through a single output window, A maximum output power of 1.7 MW has been achieved. At the nominal operational parameters an RF power of 1.3 MW with an efficiency of 27.3% has been measured, The efficiency increases to 41% in operation with a single-stage depressed collector.	en
