The article reports that The overall response to these guides has been extremely enthusiastic because they have proven to be useful for instruction, for reference, and for additional study. Previous terminology guides in the series have included such topics as Molecular Spectroscopy (2019), Raman Spectroscopy (2020), and Infrared Spectroscopy (2021).

Fundamental research often requires narrowband light to accurately map out fluorescence spectra, reaction energetics, or other key questions in chemical, biological, and physical systems. Tunable narrowband sources are often key to this endeavor. Pulsed or continuous wave, the optical parametric oscillator (OPO) has come a long way, dropping in price while improving in performance. We explore the landscape and some common uses of this essential tool for spectroscopists. [ABSTRACT FROM AUTHOR]

The article focuses on the occasion of Spectroscopy's 35th birthday would be an interesting opportunity to consider the amazing explosion in light sources for spectroscopy over the last few decades. Topics inlcude the proliferation of form factors, and a substantial increase in portability, comparing the well-funded graduate research laboratory in the early 1990s, and the light-emitting diodes has were developed at General Electric and Texas Instruments in the early 1960s.

The article reports on the study conducted by Dr. Michael Knorz, professor of ophthalmology at the University of Heidelberg, Germany, in investigating the adherence of flaps created using different techniques. It says that rabbits were used to undergo flap creation with a mechanical microkeratome or a 150 khz femtosecond laser using a side cut design and side cut energy design. He claims that femtosecond laser groups is 2.5 times greater compared to the mechanical microkeratome-created flaps.
