1.5 μm Low Phase Noise Femtosecond Laser

Precilasers' 1.5 μm low phase noise femtosecond laser adopts nonlinear amplifying loop mirror (NALM) technology to achieve long-term, high-stability pulse output, adapting to high and low temperature operating environments. To further consolidate its core advantage of low noise, the laser undergoes in-depth optimization in pump source and optical path design: through frequency and amplitude stabilization control of the pump source, low-loss coupling of the optical path, and anti-vibration structural design, it systematically reduces the intrinsic phase noise and amplitude noise of the main oscillator. Relying on innovative nonlinear spectral broadening and low-noise amplification technology, it broadens the pulse spectral bandwidth while effectively suppressing noise accumulation during the amplification process, realizing long-term ultralow phase noise and ultralow timing jitter pulse laser output. This provides core support for scenarios with strict noise requirements such as high-precision measurement and optical frequency standards.
