Spectra-Physics has introduced Spirit-OPA, an automated optical parametric amplifier (OPA) specifically optimised for use with Spectra-Physics’ Spirit high-repetition-rate ultrafast laser.  

Spirit and Spirit-OPA together create a versatile and high energy, ultrafast laser system that tunes virtually gap-free from the mid-infrared (mid-IR) to the deep ultraviolet (DUV) with user-adjustable repetition rates from tens of kHz up to 1MHz.  

The user-friendly system is ideal for high repetition rate, time-resolved spectroscopy applications such as single molecule studies, nonlinear optics and fluorescence lifetime measurements.

'Spirit-OPA pumped with the Spirit laser is a powerful tool, delivering femtosecond, micro-Joule pulses at high repetition rates across a broad spectrum,' said Julien Klein, senior manager of product marketing for Spectra-Physics.

'This advanced system enables a range of new science, allowing fast data averaging and increased signal-to-noise ratios in challenging ultrafast spectroscopy applications.'

The company has also introduced Explorer One, which it describes as one of the world’s smallest, actively Q-switched diode-pumped solid-state ultraviolet lasers, and the Quasar 355-45, a UV laser that delivers >45W (225µJ) at exceptionally high repetition rates.
