【摘要】 通过对氦-镉激光器激光噪声谱上不连续振荡噪声分量的测试,发现放电管的边界条件、放电电流和镉密度对电离波频率特征峰的功率、频率、调制度、1/f噪声范围和其余噪声均有影响。得到电离波频率特征峰处100％的调制度结果。更多还原

【Abstract】 By measuring the discontinuous oscillation components of the continuous frequency spectrum for the beam noise of He-Cd lasers, it has been discovered that the boundary conditions of the laser tube, the discharge current and Cd atom density have influences on the frequency and the power output of the characteristic peak of the ionization wave frequency, the de’pth of modulation, the 1/f noise bandwidth and other noise amplitudes. A 100% depth of modulation at that characteristic peak has been obtained.更多还原
