  • It works stably, has a 12-month warranty, and accepts small and large batch orders. It can be used in R&D, medical and industrial fields.

  • When linearly polarized light is incident precisely along one of the principal axes (slow axis or fast axis), due to the huge difference in propagation constants between the two orthogonal polarization components, almost no energy coupling occurs between them, thereby maintaining the incident polarization state.

  • ASE broadband light source works based on the principle of amplified spontaneous emission. When pump light is injected into doped optical fiber (such as erbium-doped optical fiber), the number of particles is inverted. Particles at high energy levels spontaneously transition back to low energy levels, releasing photons, which propagate in the optical fiber and induce more stimulated radiation, thereby achieving light amplification.
