Tm:YVO(4) microchip laser.
When pumped with a 1-W laser diode, a Tm:YVO(4) microchip laser produced 150 mW of 1.92-µm output in a near-diffraction-limited beam at room temperature. Using a Ti:Al(2)O(3) laser to pump the same device, we showed that reducing the temperature of the Tm:YVO(4) from 20 to -30 °C resulted in no measurable change in threshold and increased the slope efficiency by only 20%.
