7 80-femtosecond fiber laser
- Center wavelength 780±10 nm
- Repetition rate: 80 MHz
- Free-space output
The 780‑fs fiber laser series is built on perfectly automated mode‑locking, a proprietary low‑noise fiber amplification technology, highly efficient nonlinear frequency‑doubling, and robust pump‑protection circuitry, delivering exceptional long‑term stability and reliability. This family of fiber femtosecond lasers features a center wavelength of 780 ± 10 nm, a repetition rate of 80 MHz, pulse durations below 140 fs, a spectral width of 8 ± 3 nm, and output power fluctuations of less than 1%.
GHz femtosecond fiber laser
- Center wavelength 1030 nm
- Repetition rate: 1 GHz
- Pulse width < 120 fs
The GHz femtosecond fiber laser operates at a repetition rate of 1 GHz, leveraging mode-locked femtosecond pulse dispersion‑management amplification. Featuring an all‑fiber architecture and water‑cooled thermal management, it delivers long‑term stability in both pulse energy and pulse duration. The laser’s GHz square‑wave waveform offers adjustable pulse width and repetition rate, with output pulse durations below 120 fs, maximum square‑wave energies exceeding 100 mJ, and an average output power of 25 W.
Note: This laser type is water-cooled, and the shipping list includes the laser unit and the chiller.
Ultra-narrow pulse-width femtosecond fiber laser
- Center wavelength 1030 nm
- Pulse width < 50 fs
- Repetition frequency 27.5 MHz
The ultra-narrow pulse‑width femtosecond fiber laser employs all‑fiber pre‑chirp management and self‑similar amplification to generate an ultra‑broadband, ultrashort pulse. Based on an integrated opto‑mechatronic design, it offers stable output, reliable performance, and long operational life. Equipped with an intelligent pulse‑control module, the laser supports functions such as pulse frequency selection, pulse shaping, and gated output. This series delivers pulses with durations below 50 fs, single‑pulse energies exceeding 1 μJ, a repetition rate of 27.5 MHz, and an average output power of 25 W.
Femtosecond fiber seed source
Center wavelength 1030 nm
Repetition frequency 27.5 ± 0.5 MHz
Output mode: PM980 polarization-maintaining patch cord output (with FC/APC connector)
The femtosecond fiber‑seeded laser series employs an all‑polarization‑maintaining fiber architecture, a dispersion‑managed nonlinear amplification ring mirror, and intelligent mode‑locking control technology. It integrates core modules such as precise dispersion management, self‑similar pre‑amplification, parabolic spectral shaping, high‑isolation pump protection, and rapid one‑button auto‑start. The output beam of this laser series is linearly polarized, with a repetition rate… 27.5 ± 0.5 MHz , with a spectral width of 20–30 nm, the output mode is PM980 Polarization-maintaining patch cord output (with FC/APC Joint)
