Embodiment Construction
[0038] The present invention is described in detail below in conjunction with accompanying drawing:
[0039] Such as figure 1 As shown, the present invention proposes a test device and method for semiconductor laser peak optical power, wherein the device is mainly composed of high-speed photoelectric conversion and preamplification module (1), high-speed pulse light holding and sampling module (2), high-speed pulse frequency and It is composed of a widening test module (3), an FPGA control and display module (4) and other modules.
[0040]The high-speed laser pulse passes through the high-speed photoelectric conversion and preamplification module (1), which realizes the photoelectric conversion of the high-speed pulse optical signal and the preamplification of the signal. The preamplified electrical pulse signal is held and sampled by high-speed pulse light respectively. A module (2) and a high-speed pulse frequency and stretching test module (3). Among them, the high-speed ...
