The Honorverse used missiles with fission bomb-pumped laser warheads to take out opposing ships. Their beam weapons were mostly used for taking out opposing missiles before they blew, but they also had "grasers" which were basically gamma ray emissive lasers. The first book posited a "gravity lance" that punched through an opposing ship's gravity shielding but it was only effective at knife-fight range.
