The Asgard directed energy weapon was only seen once. It was provided by the Asgard Kvasir and used to cause the Stargate's wormhole to "jump", in order to shut down a conduit into an alternate reality created by an alternate SG-1. The plan was successful and the alternate SG1's plan to steal a piece of powerful technology from the prime universe was foiled. Kvasir seemed somewhat concerned about loaning the device and made certain to emphasize it was on loan, "only temporarily". (SG1: "Ripple Effect")
