摘要：
We demonstrate an electrically pumped CdZnSe/ZnSe blue-green vertical-cavity surface-emitting laser (VCSEL) with a SiO2/TiO2 dielectric multilayer mirror. Electrically pumped lasing was achieved at 77 K with a threshold current of 3 mA (pulsed). A low far-field radiation angle of 7 degrees was observed above the threshold in a 10 mu m-diameter device, which indicates the spatial coherence expected for lasing.
