Room-temperature continuous-wave upconversion laser at 455 nm in a Tm(3+) fluorozirconate fiber.
A room-temperature blue upconversion laser operating at 455 nm is demonstrated in a Tm(3+) -doped fluorozirconate fiber when the laser is excited simultaneously at 645 and 1064 nm, permitting as much as 3 mW of cw blue laser output.
