1.5 μm Narrow-Spectrum Femtosecond Laser

Precilasers' 1.5 μm narrow-spectrum femtosecond laser adopts advanced nonlinear amplifying loop mirror (NALM) technology to achieve long-term, high-stability pulse output. By precisely controlling the nonlinear phase shift and intra-loop gain, this technology effectively suppresses mode competition and intensity fluctuation, ensuring stable pulse output and spectral purity even under continuous operation. Combined with an adaptive temperature control system and environmental anti-interference design, the laser exhibits excellent adaptability to high and low temperatures. Furthermore, through optimized optical path and structure, the timing jitter is significantly reduced, enabling long-term low-noise and narrow-spectrum pulse laser output. Therefore, the laser has broad applicability in scientific research and high-end technology fields, including: Atomic and Molecular Physics Research: Used for exciting and detecting ultrafast quantum dynamics processes; Precision Measurement Systems: Serves as the core light source for optical frequency combs; Ultrafast Imaging and Spectroscopy: Supports femtosecond time-resolved imaging and transient spectroscopy analysis; Quantum Information Technology: Suitable for quantum entangled light source generation and coherent manipulation experiments; Photonic Microwave Generation: Acts as the core light source for low phase noise microwave signal generation, achieving high-purity microwave output after photoelectric conversion, and is compatible with microwave photonics, time-frequency synchronization, and radar system R&D.
