Abstract
Pulsed room‐temperature laser action at 2.06 μm has been achieved using Ho3+:YLF (LiF4) sensitized with Er3+ and Tm3+. An unoptimized cavity gave a threshold of 35 J and a slope efficiency of 1.3% in normal mode with an output mirror of 62% T. A slope efficiency of 2% and a 65‐J threshold were observed in Q‐switched operation along with Q‐switched energy of >500 mJ from a 0.9×⅛‐in. rod. The sensitizer ions have broad absorption bands and transfer times (to the active ion) of 150–200 μsec.Keywords
