OPO Tunable Pulsed Laser
Opolite series lasers are tunable nanosecond lasers mainly used for photoacoustic imaging, laser spectroscopy, LiDAR, and biomedical applications. it uses the reliable Nimma series to pump OPO module. the pumping source, OPO module, power supply, and cooling system are highly integrated into a movable cabinet, providing flexible use for customers.
The Opolite series lasers feature fully automatic control with PC operating software, motorized wavelength switching (arbitrary wavelength switching, signal and idler light switching, pump light switching), real-time energy monitoring and storage, and motorized energy attenuation. Additionally, there are such as fiber interlock, temperature monitoring, and flow monitoring to ensure reliable and safe operation.
