The trivalent thulium ion is an interesting activator for silica fiber lasers because of the near infrared transition which is broadband tunable ( diode pumpable can be operated with photon conversion efficiencies greater than 100 and has yielded in excess of 1W output power when pumped by a cw Nd:YAG laser. The paper will review progress on this system and indicate some potential future developments.
