    • A laser monitor is provided with a light sensitive component disposed near the laser and spaced apart from two windows that are generally parallel to each other. The two windows are located at positions which provide compensating reflective light beams whose power reflected back onto the light sensitive component combine to provide a relatively constant sum over a finite range of magnitudes of divergences of the laser beam. The nearest window to the light sensitive component reflects a light beam with a generally circular illuminated region having a smaller diameter than the diameter of the light sensitive component. The farther window reflects a light beam onto the light sensitive component with a diameter that is larger than the light sensitive component. As the numerical aperture of the laser increases, both illuminated circles increase in diameter and the increase in one reflected beam compensates the decrease in the other reflected beam so that the sum of the two powers falling on the detector is generally constant over the preselected range of numerical apertures. This provides a relatively constant tracking ratio that enables the light sensitive component to serve as a reliable monitor of the emitted power from the laser, which can be a VCSEL.
    • 激光监视器设置有设置在激光附近的光敏部件,并且与两个通常彼此平行的窗口间隔开。 两个窗口位于提供补偿反射光束的位置,反射光束反射回光敏元件上,其功率在激光束的发散幅度的有限范围内提供相对恒定的和。 对光敏部件的最近窗口反射具有直径小于光敏部件直径的大致圆形照明区域的光束。 更远的窗口将光束反射到光敏部件上,其直径大于光敏部件。 随着激光器的数值孔径的增加,两个照明圆的直径都增加,一个反射光束的增加补偿了另一个反射光束的减小,使得落在检测器上的两个光功率的和通常在预选的范围内是恒定的 数值孔径。 这提供了相对恒定的跟踪比,其使得光敏部件能够用作来自激光器(其可以是VCSEL)的发射功率的可靠监视器。
