Svendsen may have claimed two relay titles at last year's World Championships in Ruhpolding however he had to settle for silver behind Frenchman Fourcade in the sprint.
He got this year's campaign off to a winning start as Norway's mixed relay team defended their title with Fourcade's France second before getting one over him for the sprint defeat 12 months ago.
Both missed one target, that coming in the standing shoot, however Svendsen was quicker around the course to win his first sprint world title by 8.1seconds over Fourcade in second.
Svendsen faced a nervous wait for confirmation though as Dmitry Malyshko and Jakov Fak shot clear while Ole Einar Bjoerndalen made a charge to add to his massive World Championship medal haul.
None could better his time though as Svendsen took his all-time World Championship medal tally to 14, nine of which are wins, with Fourcade claiming silver and Fak bronze.
Fourcade, who himself has won nine world medals, including four gold, started two minutes ahead of Svendsen and posted the quickest time of 23:33.2minutes to temporarily sit in first place.
However Svendsen was quicker than him over almost every split to clock 23:25.1 before watching on as the Malyshko, Fak and Bjoerndalen attempted to overthrow him.
Neither of the three could though, nor could they get the better of Fourcade, with Fak occupying the final step of the podium 11.2 behind Svendsen and 3.1 behind Fourcade.
Bjoerndalen was a further 8.7 adrift for fourth, a missed target on the standing shoot costing him dear, while Malyshko came in 23.2 behind in total for fifth in the Czech Republic.
