  • High power semiconductor laser

    Semiconductor laser has the advantages of small size, light weight, high electro-optical conversion efficiency, high reliability and long life. It has important applications in the fields of industrial processing, biomedicine and national defense.

  • Dense Wavelength Division Multiplexing

    DWDM: Dense Wavelength Division Multiplexing is the ability to combine a group of optical wavelengths and use a single optical fiber for transmission. This is a laser technology used to increase bandwidth on existing fiber optic backbone networks. More precisely, the technology is to multiplex the tight spectral spacing of a single fiber carrier in a specified fiber in order to utilize the achievable transmission performance (for example, to achieve the minimum degree of dispersion or attenuation). In this way, under a given information transmission capacity, the total number of optical fibers required can be reduced.

  • Near infrared spectrometer

    The near-infrared spectrum is mainly generated when the molecular vibration transitions from the ground state to a high energy level due to the non-resonant nature of the molecular vibration. What is recorded is mainly the frequency doubling and combined frequency absorption of the vibration of the hydrogen-containing group X-H (X=C, N, O). . Different groups (such as methyl, methylene, benzene rings, etc.) or the same group have obvious differences in the near-infrared absorption wavelength and intensity in different chemical environments.

  • What is EPON?

    With the rapid development of the Internet, network users' demands for network bandwidth are increasing day by day. In order to meet the needs of the market, the backbone of the communication network has undergone tremendous changes, and the traditional access network that has been changing less has become a bottleneck in the entire network, and various new broadband access technologies have become research hotspots.

  • Scientists have developed a new type of laser

    Scientists have developed a new type of laser that can generate a lot of energy in a short period of time, which has potential applications in ophthalmology and heart surgery or fine materials engineering. Professor Martin De Steck, director of the Institute of Photonics and Optical Sciences at the University of Sydney, said: The characteristic of this laser is that when the pulse duration is reduced to less than one trillionth of a second, the energy can also be "instantly "At its peak, this makes it an ideal candidate for processing materials that require short and powerful pulses.
