The Spirit® femtosecond laser is a flexible, high repetition rate one box ultrafast
amplifier. With direct diode pumped technology developed by Spectra-Physics,
Spirit’s innovative and simple architecture offers truly unique performance.
The Spirit platform offers impressive versatility to serve the needs of scientific and
industrial customers. The laser’s high average power (>16 W) and high repetition rate
enable fast data acquisition in complex time resolved spectroscopy experiments. Pulse
energy and repetition rate adjustability (single shot – 1 MHz) make the Spirit laser ideal
for medical device manufacturing and femtosecond micromachining. The amplifier is
optimized for one factory calibrated repetition rate between 100/200/400 kHz (40 µJ)
and 1 MHz (4/8/16 µJ), depending on the laser model. This basic repetition rate can
be chosen by the customer. Additional pre-set repetition rates are optional and can be
configured in the factory during assembly upon request. The integrated pulse picker
offers the possibility for fast pulse selection and power control by an analog input
signal. This simplifies the integration of the laser and offers fast process throughput.
The optional, high efficiency Second Harmonic Generation (SHG) module enables
the fabrication of smaller and more accurate structures. The fundamental and SHG
output beams are collinear at the laser exit for easy integration and beam delivery. The
end user can easily switch between the 1040 nm and 520 nm outputs by software.
Fully automated and computer controlled, Spirit is manufactured with high reliability
and quality in mind. Spirit’s design is optimized for easy integration and for the
superb power and beam pointing stability (typically <20 µrad for 100 hours) during
24/7 operation, ensuring high precision and reproducibility in every application.
