Latest Patents

Zhonghong Jiang holds a patent for a "Tunable narrow-linewidth single-frequency linear-polarization laser device." This device comprises a heat sink, a pumping source packaged on the heat sink, a first and second collimating lenses, a laser back cavity mirror, a thermal optical tunable filter, a rare-earth-ion heavily-doped multicomponent glass optical fiber, a super-structure polarization-maintaining fiber grating, a polarization-maintaining optical isolator, a polarization-maintaining optical fiber, and a thermoelectric refrigerating machine. The laser device utilizes a short and straight single-frequency resonant cavity structure, leveraging the heavily-doped and high-gain characteristics of the multicomponent glass optical fiber. It incorporates a frequency selection role and wavelength tuning function of the thermal optical tunable filter and the superstructure polarization-maintaining fiber grating. Additionally, it combines precision temperature adjustment technology, allowing for real-time adjustment of the distribution of reflection wavelengths and transmission wavelengths. This results in the ability to change spectrum peak overlapping positions, enabling stable output of a wide-tuning-range, extra-narrow-linewidth, high-extinction-ratio, and high-output-power continuously tunable single-frequency linear-polarization laser.
