We tested spectrum of 3 comet lasers. Each laser are connected to one of the vertical pumping fibers. And the specturm shown below are actually "absorption specturm" after the cell. However, Comet laser wavelength width are so narrow that no "absorption peak" can be ssen. The working condition are Rutgers@34A.20C WM@35A.26C JLab@36A.25C
