Tunable Lasers Expand for Time-Resolved Spectroscopy

Many research labs are turning to tunable lasers, or optical parametric oscillators (OPOs), for nanosecond time-resolved spectroscopy. OPOs have long been utilized in sophisticated test and measurement applications such as mass spectrometry and photoacoustic imaging. Read on to learn why these tunable pulsed lasers are being utilized.

Their device, which is only a few centimeters in size, can be manufactured at scale in batches and then incorporated into a mass spectrometer using efficient, pick-and-place robotic assembly methods.

OPO Lasers: Putting Optical Components to the Test

Optical parametric oscillator (OPO) lasers test optical fibers and components to characterize the spectral response of optical components. Now, these tunable pulsed lasers are being used to facilitate a range of tests at different wavelengths to qualify and quantify the performance of optical components such as fiber optic strands, filters, lenses, and coated mirrors.
