| Zusammenfassung | The paper reports on upconverted orange (607.5nm, 3P0 → 3H6) and red (638.7nm, 3P0 → 3F2) laser oscillation at room temperature observed in Pr3+, Yb3+:BaY2F8 under excitation at 822nm or 841nm at 300K. The upconversion mechanism that populates the emitting level is an avalanche excitation mechanism. Output powers up to 55mW and slope efficiencies up to 27% were demonstrated at 607.5nm. At 638.7nm the maximum output power was 26mW with a slope efficiency of about 13.5%. |
