The STC-Spark-OPO and STC-Spark-OPO-HP is
a near to mid-infrared quasi-CW optical parametric
oscillator. It provides exceptional tunability and power
across the near-infrared, making it an ideal light source
for a wide range of application areas (from multi-photon
microscopy to spectroscopy). Our ultrafast optical
parametric oscillator technology can generate light from 1.4
�m to 4.2 �m with picosecond pulsewidths. With a fully
integrated pump source it is able to deliver high average
power at both the signal and idler wavelengths with
exceptional reliability. We also provide access to the fixed
wavelength pump light, making it suitable for CARS
microscopy.

STC-Spark-OPO-FIR
The STC-Spark-OPO-FIR is the world�s
first commercial broadband ultrafast OPO providing output in
the 5 � 12 �m region. In the 5 � 7 �m region up to 80 mW can
be achieved and at 12 �m up to 10 mW of light is available.
The Spark FIR is an ideal source for spectroscopy in the
molecular fingerprint region as well as stand-off detection
and remote sensing applications.
