IMPULSETM "PhaseShifter" Synchronizable High-Average-Power Laser


IMPULSETM “PhaseShifter” is an all-diode-pumped, direct-diode-pumped, Yb-doped fiber oscillator/amplifier system capable of producing variable pulse energies up to 10 μJ with user-selectable repetition rate between 200 kHz1 and 25 MHz. With 20 watts average power output at 2 MHz, IMPULSETM offers more than an order-of-magnitude higher power than has traditionally been available in a one-box ultrashort pulse laser design.

IMPULSETM 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 associated with solid-state operation with high spatial mode quality of fiber lasers.

IMPULSETM is a compact, robust, one-box source of femtosecond to picosecond pulses with the ease-of-operation, stability and reliability you expect from a fiber source. All major parameters are computer controlled, which allows easy interface to workstation or experiment. IMPULSETM is synchronizable to external reference through electronic control of both frequency and phase. It is even iPhone/iPod2 App enabled.

Optional accessories include multi-photon photo-polymerization, waveguide writing, micromachining, harmonic generation, and OPA/NOPA wavelength conversion.
