Miniature diode-pumped Nd:YAlG lasers (Miniaturized Nd-YAG laser end pumped by single incoherent gallium-arsenide-phosphide light emitting diode to achieve threshold at room temperature)
A miniaturized Nd:YAlG laser is described, in which a 5 x 0.45-mm laser rod is end pumped by a single incoherent GaAs(1-x)P(x) light-emitting diode. Laser threshold was achieved at room temperature in a pulse pumped mode of operation. The measured threshold optical power incident on the end of the l...

| Zusammenfassung: | A miniaturized Nd:YAlG laser is described, in which a 5 x 0.45-mm laser rod is end pumped by a single incoherent GaAs(1-x)P(x) light-emitting diode. Laser threshold was achieved at room temperature in a pulse pumped mode of operation. The measured threshold optical power incident on the end of the laser rod was 19 mW at 24 C. Based on an extrapolation from known Ga(1-x)Al(x)As diode performance, it is concluded that present technology can provide diode pumps to drive a miniature Nd:YAlG laser 2.4 times above threshold continuously at room temperature. |
