N. Yamada et al., CONTINUOUS-WAVE OPERATION OF A BLUE VERTICAL-CAVITY SURFACE-EMITTING LASER-BASED ON 2ND-HARMONIC GENERATION, Applied physics letters, 68(14), 1996, pp. 1895-1897
An InGaAs/GaAs vertical-cavity surface-emitting laser has been fabrica
ted on a (311)B GaAs substrate. Pulsed lasing operation is obtained at
room temperature, and continuous-wave lasing operation is obtained at
less than 270 K. From the device, blue laser emission based on second
-harmonic generation is observed. The wavelength of the blue laser emi
ssion is 482 nm. At 135 K, its output power is 1 nW under continuous-w
ave operation and more than 10 nW under pulsed operation. (C) 1996 Ame
