Abstract
The wavelength of laser emission from an electron‐beam‐pumped ZnO was measured in the temperature range from 82 to 250°K. The laser emission occurred near the line due to the annihilation of a free exciton assisted by one LO phonon at 82°K. Above 180°K the laser emission occurred near the line due to the transition assisted by two LO phonons. From 130 to 170°K the laser oscillation appeared in two spectral lines. The temperature dependence of threshold current density measured from 82 to 250°K was weak compared with the theoretical curve based on the laser action involving the A‐LO line.Keywords
