摘要：

We report the use of a positive branch self-filtering unstable resonator (PB/SFUR) with a copper vapor laser (CVL). The performance of this resonator is compared with that of a positive branch unstable resonator (PBUR) CVL. In the case of the PB/SFUR CVL about 70% of the output power is contained in the diffraction limited divergence angle as compared to only about 10% for PBUR CVL. The analysis of the temporal behaviour of the output pulses indicates that the PB/SFUR starts influencing the laser pulse characteristics very early during the pulse.
