FemtoFiber ultra 780
Femtosecond fiber laser
TOPTICA's industrial-grade, compact, turn-key, and robust fiber-laser technology provides highest intrinsic stability and allows for deep integration of the light source into your equipment. The excellent spatial beam profile guarantees unmatched focusability and resolution, enabling you to unlock the true potential of your application. Sufficient power, short pulses, and an extremely clean temporal pulse shape combined with options for dispersion compensation and power control make the FemtoFiber ultra 780 the ideal choice for next generation two-photon polymerization and semiconductor analysis.
Your Benefits
Powering the fastest two-photon lithography
Highest available power for a commercial fiber laser at 780 nm on the market. The system has outstanding 1 W and allows pulses in the range of 150fs. If that is too long, we can go down to 80 fs duration with the Short Pulse (SP) option. If the output power needs to be higher, we can also optionally go for 1.5W with the High Power (HP) option.
Super-compact cold laser head
Small-sized laser head with minimum heat dissipation. The laser head includes all free-space optics of the system, holding them in a 77 x 165 x 300 mm³ sized housing, with a low weight of just <6 kg. It allows also to mount the head vertically.
Fully software controllable system
Python-scripting compatible system with GUI and/or development SDK for system integrators. The laser allows to be operated by remote control, having no need to manually interact with the system. The software allows also to monitor the laser during long-term operation 24/7.
More than 20 years of experience
TOPTICA is drawing upon 20 years of experience in developing OEM-class fiber lasers. We have tailored our FemtoFiber ultra series to provide our customers with an industrial-grade light engine for high-end applications. The reliable and compact laser design provides femtosecond pulses with high average power, excellent temporal and spatial beam quality.
Low cost of ownership
Robust & reliable fiber laser technology significantly reduces the cost of ownership. The laser systems require no chiller and have low power consumption. In addition, the quiet & compact laser design minimizes noise-stress to the animals while at the same time saving valuable table space.
Options
SP-Option
System with optimized pulse duration below 100 fs, typ. 80 fs reachable
HP-Option
System with optimized output power of up to 1.5 W
AOM-Option
Integrated AOM for fast modulation of the laser light, integrated to the system
PulsePicker-Option
Integrated pulse picker to reduce the effective repetition rate from 80 MHz down to 1:10, 8 MHz
Custom Rep Rate-Option
Customization of the factory-preset repetition rate of the system. Nominally, anything in between 50 - 80 MHz can be configured. Repetition rates below/beyond this range are on request
FemtoFiber ultra 390
System with additional SHG united factory-premounted to the system, allowing to generate 390 nm femtosecond pulses, but also being switchable to 780 nm
FemtoFiber ultra 1550
System without internal SHG to 780 nm, but only fundamental Er doped fiber amplifier output with 1550 nm center wavelength
Dual-color
With the FemtoFiber ultra dual-color option two FemtoFiber ultra are optically synchronized and allow simultaneous imaging with two different laser colors. No laser wavelength tuning is required. A shared oscillator design guarantees all-optical synchronization and hence a fixed, defined delay between the two laser colors with minimum jitter. The Femto Fiber ultra can also be optically synchronized to the FemtoFiber dichro, FemtoFiber smart or TeraFlash pro.
