Introduce the optical system for laser emission and reception
Introduce the optical system for laser emission and reception The laser emission and reception optical system consists of two major parts: the emission optical module and the reception optical module. Its most widely applied fields are laser processing systems, fluorescence detection syste...Read More -
What factors affect the wavelength of laser?
What factors affect the wavelength of laser? The wavelength of laser is not determined by a single factor, but is jointly determined by its core physical mechanism (stimulated radiation) and specific structural design. The core depends on the energy level structure of the working substance...Read More -
The new type of photodetector detects weak light signals in the 2μm band
The new type of photodetector detects weak light signals in the 2μm band In many cutting-edge fields of scientific research and industrial applications, the precise capture and analysis of weak light signals have always been the key to driving technological innovation. Especially in the 2-...Read More -
The main characteristics of lasers
The main characteristics of lasers The generation of lasers The theory of “spontaneous and stimulated radiation” proposed by Einstein in 1916 is the physical foundation of modern laser system. The interaction between photons and atoms may cause three types of transition process...Read More -
Introduce the new type of single sideband modulator
Introduce the new type of single sideband modulator In the field of optical communication and radio frequency integration, how to break through the dispersion bottleneck of traditional modulation modules and enhance the stability and convenience of signal transmission has always been the core iss...Read More -
Minimization of the laser linewidth
Minimization of the laser linewidth The linewidth of a laser is directly related to the type of laser. The laser linewidth can be minimized by optimizing the laser design and minimizing the influence of external noise as much as possible. The first step is to determine which is dominant, q...Read More -
Line width measurement of narrow-linewidth laser
Line width measurement of narrow-linewidth laser The linewidth of narrow-linewidth laser, especially that of single-frequency lasers, refers to the width of the laser spectrum (usually half-width to full-width FWHM). More precisely, the width of the power spectral density of the radiated e...Read More -
Avalanche photodetector: Captures clear light signals
Avalanche photodetector: Captures clear light signals A data torrent of 10Gb per second surges through optical fibers. The weak optical signals are like fireflies in the deep sea. How can they be precisely captured and amplified? The Rofea Optoelectronics’ newly launched ROF-APR 10G high-sp...Read More -
Introducing the “Soul” of solid-state lasers
Introducing the “Soul” of solid-state lasers Mainstream solid-state laser materials The core of any laser is the laser working substance, and the working substance of a solid-state laser is essentially solid. Most solid-state laser media are composed of crystal matrices and dop...Read More -
The medical applications of laser
The medical applications of laser Laser treatment 1. Laser surgery: Laser surgery uses conventional surgical instruments with laser beams instead of metals to separate, cut, remove, coagulate, weld, drill holes, and perform osteotomy on tissues to remove lesions and anastomose tissues, blood ves...Read More -
The core structure of a single-mode fiber laser
The core structure of a single-mode fiber laser The outstanding performance of single-mode fiber laser stems from their precise internal structure design. The efficient collaborative operation among all components is the foundation for achieving stable and high-quality laser output. For in...Read More -
The basic principle of single-mode fiber lasers
The basic principle of single-mode fiber lasers The generation of laser requires meeting three basic conditions: population inversion, an appropriate resonant cavity, and reaching the laser threshold (the gain of light in the resonant cavity must be greater than the loss). The working mechanism o...Read More
