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 -
