Polarization spectra of rubidium atoms were investigated with different uncrossed angles between the polarizer and the analyzer. The variation of the spectra was derived theoretically as a function of arbitrary angle, and measured experimentally for different angles. The spectral profile of D_(2) line of rubidium was further used to stabilize the frequency of a diode laser. It was demonstrated that the laser linewidth was reduced to 2 MHz.

本文报道了外腔中半导体激光器的双频振荡现象.这种现象起因于两束反馈光线——一束通过有源区,一束通过无源区——之间的干涉效应.由此亦可解释可调谐布儒斯特角半导体激光器的输出功率对波长曲线上的调制现象.

在各种不同用途的电子束仪器(电视显像管、示波管、字符图象显示器)中广泛使用半导体化合物在加速电子作用下发光。为此一般采用掺杂半导体(荧光粉),它的辐射由电子通过激活剂杂质形成的能级的跃迁产生。在电子束流比较小时,现代荧光粉的量子输出也趋近极限。但是,它们也有重大的缺点:随着电子束电流密度的增大,辐射强度也达到饱和、光的漫散射、辐射光谱较宽,而且有余辉。这些缺点限制了发光亮度,阻碍了光斑的扫描速度的增加,大大降低了利用效率,并排除了荧光粉在相干光学装置中的可能应用。
