Reach high power levels with TOPTICA’s next generation femtosecond fiber lasers

toptica FemtoFiber ultra NIR 02

TOPTICA’s FemtoFiber ultra NIR provides powerful femtosecond pulses of more than 500 mW and less than 150 fs at 780 nm.

The FemtoFiber ultra NIR from TOPTICA is a cost-effective, turnkey laser system that provides femtosecond laser pulses of more than 500 mW average power and an excellent beam quality. It is a powerful solution for applications in nonlinear microscopy like effective two-photon excitation of fluorescent proteins and SHG based contrast mechanisms, as well as micro-lithography. Experiments in fundamental physics will also benefit from the high output power of the laser. It provides pulses with a spectrum centered at 780 nm and a duration below 150 fs.

The system integrates a patented SESAM-mode-locked fiber-ring oscillator and a new high-power fiber amplifier. Polarization-maintaining, active fibers are used in order to maintain the highest reliability levels. Based on a fundamental wavelength of 1560 nm with a repetition rate of 80 MHz for oscillator and amplifier, the FemtoFiber ultra NIR uses a frequency-doubling stage, which converts the amplified output spectrum to 780 nm. Due to a highly efficient frequency-conversion process, more than 500 mW average power is available at 780 nm with a clean TEM00-mode free-space output.

The laser requires no water-cooling for a stable operation. It can be controlled easily via Ethernet connection with a simple GUI that enables user-friendly access to all laser parameters.

The FemtoFiber ultra NIR is the first member of TOPTICA’s third generation of ultrafast fiber lasers. This “ultra”-series contains an improved concept for laser and electronics, combined with the fresh look and feel of a new silver housing.

Specifications:

  • Center wavelength: 780 nm
  • Pulse duration: < 150 fs
  • Laser output power: > 500 mW
  • Repetition rate: 80 MHz
  • Output coupling: Free space
  • Footprint: 22 x 38 cm²
  • Communication via Ethernet
