A laser bar is an array semiconductor laser chip integrated with dozens of emitters, which realizes hundred-watt quasi-continuous output on a single chip. With regular emitter arrangement and controllable fill factor, integrated thermal design and superior wall-plug efficiency compared to single chips, it acts as the core light source for high-power pumping, medical lasers and precision processing.
Driven by the continuous pursuit of higher precision and efficiency in optical communication and optoelectronic device manufacturing, OLCR-1000 Low-Coherence Interferometer, independently developed by Wuhan Guanggu Interconnect Technology Co., Ltd., provides an innovative technical solution for distributed return loss testing of optical fibers and optoelectronic devices.
Fluoride crystal glass and K9 optical glass are two core optical substrates widely used in precision optical systems, laser equipment and photoelectric scientific research.
For pulsed laser and full-spectrum optical testing, photodiodes and thermopiles have inherent drawbacks. Photodiodes show weak response in infrared band, while thermopiles feature slow response and cannot capture nanosecond narrow pulses.
