TM-YVO4 MICROCHIP LASER

摘要

When pumped with a 1-W laser diode, a Tm:YVO4 microchip laser produced 150 mW of 1.92-mu m output in a near-diffraction-limited beam at room temperature. Using a Ti:Al2O3 laser to pump the same device, we showed that reducing the temperature of the Tm:YVO4 from 20 to -30 degrees C resulted in no measurable change in threshold and increased the slope efficiency by only 20%.
