OPOTEK is featured in the September 2026 issue of Medical Design Briefs in “100-Hz Laser Sharpens Detection of Short-Lived Molecular Dynamics,” by Eric Kennehan, PhD, co-founder and CEO of Magnitude Instruments.
In Medical Design Briefs, Kennehan discusses why higher-repetition-rate tunable lasers are becoming a practical priority for nanosecond transient absorption spectroscopy, particularly when researchers need to detect weak transient signals without subjecting sensitive samples to unnecessarily high excitation energy.
The key takeaway: 100 Hz operation can improve signal averaging and data quality, shorten kinetic-map acquisition, and support lower laser fluence, while tunability gives researchers more precise control over excitation wavelength.
“At higher repetition rates, more pump-probe pulses can be collected in less time with fewer variances in the entire system, thus improving the signal-to-noise ratio and enabling the use of lower pulse energies. Gentler excitation conditions reduce the risks of cumulative heating or photodamage and shorten the time required to obtain a full kinetic map.”
Kennehan also notes a product-level design advantage:
“The compact footprint of the Opolucis C was particularly compelling, as reducing overall system size remains a central design objective for Magnitude Instruments.”
