Company Profile

Established in 2017, Precilasers is a high-tech enterprise in Shanghai. PreciLasers dedicates to the research and development of precision fiber lasers for scientific research and emerging new industries such as quantum information, LIDAR, and precision processing etc. We provides high-end laser products with precise tailoring in wavelength, linewidth, or low noise etc.

Key Technologies

Ultra-narrow linewidth DFB fiber laser

A distributed feedback fiber grating is written on a gain fiber to generate single frequency laser with ultra-narrow linewidth. The excellent long-term stability of the seed laser without mode hopping is achieved by utilizing unique packaging technology.

High power narrow linewidth fiber amplifier

With excellent SBS and relative intensity noise suppression technology, fiber amplifier with up to 120 W power, excellent relative intensity noise and wide wavelength range covering (1010-2051nm) could be achieved.

Frequency conversion with high power and efficiency

High efficiency frequency converted laser extend the wavelength coverage of fiber lasers to visible, ultra violet and even Mid-IR. The stable single pass frequency conversion and high power resonant frequency conversion make fiber laser based single frequency laser more suitable for various industrial application.

High performance pulsed fiber laser

With knowledge in nonlinear fiber optics, highly reliable ultrafast fiber lasers are developed. With high speed electrical technology, stable nanosecond laser at IR, visible and UV could be supplied.
