The solution is used to copy archivelogs from RMAN catalog.
Step 1: uncatalog the required archivelogs from RMAN prompt
RMAN>CHANGE ARCHIVELOG FROM LOGSEQ=60 UNTIL LOGSEQ=70 UNCATALOG;
Once the archivelogs have been successfully uncataloged, you are now able to successfully restore the archive logs to a new location.
set archivelog destination to '/tmp/arch';
restore archivelog from logseq=60 until logseq=70;
Cataloging archivelogs again by added them to the RMAN repository
RMAN>CATALOG ARCHIVELOG '/opt/log/1_60_archivelog.log';
Cataloging multiple copies in a directory
RMAN>CATALOG START WITH '/opt/log';
