Spectra-Physics has introduced Spirit, a compact industrial-grade ultrafast amplifier with software-adjustable repetition rates up to 1MHz. Developed at High Q Laser (recently acquired by Newport), the Spirit laser extends Spectra-Physics’ ultrafast amplifier portfolio to high-repetition rates needed for micromachining of medical devices and other materials, nanostructuring, pump-probe experiments, and selected time-resolved science applications.

The Spirit ultrafast laser provides high average power of >4W and fully-automated adjustability over a wide range of repetition rates from 50kHz to 1MHz. Featuring a rugged one-box design, the laser delivers ultrashort 400fs pulse widths with high energy of 20uJ per pulse. The highly reliable Spirit also has excellent beam characteristics with diffraction-limited TEM00 mode.
