Pulsed Erbium-doped Fiber Amplifier Manufacturers

Box Optronics 760nm 10mW butterfly laser utilizes a multi-quantum well distributed feedback (MQW-DFB) structure, ensuring a precise and stable 760nm wavelength with a narrow linewidth of less than 2MHz.

Since Maman first obtained laser pulse output in 1960, the process of human compression of laser pulse width can be roughly divided into three stages: Q-switching technology stage, mode-locking technology stage, and chirped pulse amplification technology stage. Chirped pulse amplification (CPA) is a new technology developed to overcome the self-focusing effect generated by solid-state laser materials during femtosecond laser amplification. It first provides ultra-short pulses generated by mode-locked lasers. "Positive chirp", expand the pulse width to picoseconds or even nanoseconds for amplification, and then use the chirp compensation (negative chirp) method to compress the pulse width after obtaining sufficient energy amplification. The development of femtosecond lasers is of great significance.

Accurate and real-time detection of methane gas becomes critical for natural gas pipelines leakage monitoring, household safety and coal mining safety production monitoring.

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.
