>20 Watts Average Power Ultrashort Pulse Laser

IMPULSE™ is an all-diode-pumped, direct-diode-pumped Yb-doped fiber oscillator/amplifier system capable of producing variable pulse energies up to 10 microjoules at repetition rates between 200 kHz1; and 25 MHz (20 Watts average power output at 2 MHz.) This is more than an order-of-magnitude higher 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 use of a Yb-doped fiber-oscillator/fiber-amplifier design combines the low noise performance associated with solid state operation with the high spatial mode quality of fiber lasers.

IMPULSE™ is a compact, robust source of femtosecond pulses with the ease-of-operation, stability and reliability you would expect from a fiber source. And all its major parameters are computer controlled, which allow it to be easily interfaced to your industrial workstation or experiment. Optional accessories include micromachining workstations, harmonic generators, and OPA/NOPA wavelength converters.
