IMPULSE Phaseshifter
Synchronizable, High-Average-Power
Femtosecond Laser
IMPULSE™ “PhaseShifter™” is an all-diode pumped, direct-diode pumped, Yb-doped fiber oscillator/amplifier system producing variable pulse energies up to 10 μJ with user selectable repetition rate between 200 kHz1 and 25 MHz. With 20 W average power output at 2 MHz, IMPULSE™ offers more than an order-of-magnitude higher power than has been traditionally available in a one-box ultrashort pulse laser design.
IMPULSE™ is based on a revolutionary new concept in mode-locked oscillator/amplifier technology. The Yb-doped fiber-oscillator/ fiber amplifier design combines low noise performance of solid-state operation with high spatial mode quality of fiber lasers.
IMPULSE™ is a compact, robust, one-box source of femtosecond to picosecond pulses with ease-of-operaJon, stability and reliability expected from a fiber source. All major parameters are computer controlled, enabling easy interface to your experiment. It is even iPhone/iPod* App enabled.
The PhaseShifterTM version of IMPULSE™ is synchronizable to external reference through electronic control of both frequency and phase. The repetition rate of the oscillator is fine-tuned via an active element, and can be synchronized to the trigger signal of an external RF source. The phase can be varied continuously, allowing the amplified optical pulse to be locked to the external source. The electronics (phase adjustment and frequency offset) can also be used in asynchronous sampling mode.
Optional accessories include mulJ-photon photo-polymerizaJon, waveguide wriJng, micromachining, harmonic generaJon, and OPA/NOPA wavelength conversion for high S/N and rapid data acquisition in pump/probe experiments.
