Spectra-Physics (Santa Clara, CA) has introduced Spirit™ 8 W, an industrial-grade high power femtosecond (fs) laser for micromachining applications. The Spirit ultrafast laser provides high average power of >8 W in the infrared at 1040 nm with a second harmonic option for generating green femtosecond pulses. The laser delivers ultrashort 400 fs pulse widths with high pulse energies of >40 μJ and is adjustable via computer over a wide range of repetition rates from single shot up to 1 MHz. The highly reliable Spirit is fully automated and has excellent beam characteristics with diffraction-limited TEMoo mode.
