SW-PFL-1572 Series Narrow-Linewidth Pulsed Fiber Laser RS-L-1572-150
The SW-PFL-1572 is a 1572nm narrow-linewidth pulsed fiber laser for coherent heterodyne differential-absorption CO₂ detection. It time-multiplexes two wavelengths through one output: one at the CO₂ absorption-line center and one nearby where absorption is negligible. Single-pulse energy exceeds 80y」. Output is linearly polarized with very high extinction ratio, long coherence length, low noise and excellent beam quality. It operates 24h continuously in most harsh environments and is an ideal source for CO₂ detection. Lasers for differential absorption of other gases can be customized.

A microlens array (MLA) is a high-precision optical component composed of hundreds or thousands of tiny, uniformly arranged micro lenses on a single flat substrate. Unlike traditional single lenses that focus one light beam, a microlens array can split, homogenize, and reshape light on a micro scale. It is widely paired with VCSELs, lasers, and image sensors, becoming a core part of modern miniature optical systems.
