1) Single-Wavelength-line oscillation using a Lameller type reflectorSingle line oscillation was achieved by an optical resonator consisting of a Lameller type interference reflector and a concave mirror.2) Single-wavelenth-line oscillation using a capacitive mesh mirrorSingle line oscillation was achieved also by a combination of a capacitive mesh mirror faricated on a silicone-single-crystal substrate and a concave mirror.3) High-resolution spectrum measurement by a heterodyne detectionSelf-beat signal of simultaneous oscillating lines was detected with real-time- and wavelength-resolutions of 0.1 sec and 1MH_z, respectively, by operating a spectrum analyzer in a pulsed mode. The measurements revealed that line width of individual oscillation lines is extremely narrow, being around 4MH_z.4) Improved Characteristics of Oscillation in Voight ConfigurationLaser oscillation was achieved in Voight configuration, in which magnetic field is applied perpendicular to the axis of the optical resonator. This choice of configuration has led to significant improvements of the performance, such as a development of oscillation wavelength range, an increase in the intensity of long-wavelength oscillations, and an expansion of electric- and magnetic-field ranges for oscillation.

1)采用Lameller型反射镜的单波长线振荡采用由Lameller型干涉反射镜和凹面镜组成的光学谐振腔实现了单波长线振荡。2）采用电容性网状镜的单波长线振荡也是采用在硅单晶衬底上制作的电容性网状镜和凹面镜的组合实现的。3）高波长线振荡。通过外差检测的分辨率光谱测量通过在脉冲模式下操作光谱分析仪，同时振荡线的自拍信号分别以0.1sec和1MH_z的实时和波长分辨率被检测。测量结果表明，单个振荡线的线宽非常窄，约为4MHz。4）改进的Voight结构的振荡特性在Voight结构中实现了激光振荡，其中施加的磁场垂直于光学谐振腔的轴。这种配置的选择导致了性能的显著改善，例如振荡波长范围的发展、长波长振荡强度的增加以及用于振荡的电场和磁场范围的扩展。
