Miniature Nd-pentaphosphate laser with bonded mirrors side pumped with low-current-density LED’s
A laser made of a 1-cm-long Nd0.75La0.25P5O14 crystal with bonded mirrors has been side pumped with two arrays of light-emitting Al0.1Ga0.9As planar diodes in a double cylindrical-elliptical cavity. Pulsed operation (0.6 ms) is obtained at −13.5 °C, and cw lasing at −49 °C, with LED current densitie...

| Zusammenfassung: | A laser made of a 1-cm-long Nd0.75La0.25P5O14 crystal with bonded mirrors has been side pumped with two arrays of light-emitting Al0.1Ga0.9As planar diodes in a double cylindrical-elliptical cavity. Pulsed operation (0.6 ms) is obtained at −13.5 °C, and cw lasing at −49 °C, with LED current densities of 700 and 270 A cm−2, respectively. |
