A Fabry-Perot wavemeter for analyzing a pulsed laser operating in a single longitudinal mode with an injection-seeding technique has been constructed with an array detector. This wavemeter permits the real-time measurement of both the wavelength and the spectral effectiveness of the laser pulse produced at 10 Hz. The performance of the wavemeter is checked with a frequency-stabilized He-Ne laser and a double Nd:YAG laser that operates in the single longitudinal mode. The precision of the wavemeter is found to be < 10 MHz. Also, we calculated the uncertainties in determining the wave number by processing a Fabry-Perot fringe pattern imaged on a linear-array detector. The calculation is done by changing the number of pixels of the array detector, the finesse of the Fabry-Perot étalon, the waist of the incident laser beam, and the magnitude of random noise.
我们利用阵列探测器构建了一台法布里-珀罗波长计，用于采用注入种子技术分析单纵模工作的脉冲激光器。该波长计能够实时测量以10 Hz频率产生的激光脉冲的波长和光谱效率。使用频率稳定的氦氖激光器和单纵模工作的双Nd:YAG激光器对波长计的性能进行了检验。结果发现该波长计的精度小于10 MHz。此外，我们通过处理线性阵列探测器上成像的法布里-珀罗条纹图案，计算了确定波数时的不确定度。计算过程中改变了阵列探测器的像素数量、法布里-珀罗标准具的精细度、入射激光束的束腰以及随机噪声的大小。
