COMPLETE SYSTEMS – IMPULSE PHASESHIFTER
IMPULSE™ PhaseShifter
Megahertz Synchronization Femtosecond High-Average-Power Fiber Laser
IMPULSE™ “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, IMPULSE™ offers more than an order-of-magnitude higher power than has traditionally been 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 associated with 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 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. IMPULSE™ 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.
1 Optional pulse picker available to adjust repetition rate in the range of single-shot to 200 kHz.
