High-speed circuit for laser diodes
This paper attempts to describe a laser diode driver circuit using the depletion mode gallium nitride high electron mobility transistor (D-mode GaN HEMT) to generate nanosecond pulses at a repetition rate up to 10 MHz from the vertical-cavity surface-emitting laser (VCSEL). Gallium nitride (GaN) power FETs and ICs have demonstrated order-of-magnitude improvements in performance figures-of-merit over silicon MOSFETs while achieving cost parity to silicon on an equal voltage and RDS(on) basis. The key improvements are increased switching speed and decreased size. In laser sensor and measurement applications the challenges of the design of fast driver circuits is a very demanding task. I came across the following circuit in a paper which.

Can laser diodes treat viruses
Irradiation with ultraviolet light-emitting diodes (UV-LEDs) represents a promising method for viral inactivation, but a detailed understanding of the wavelength-dependent action spectra remains limited, particularly across different viral components. Long before the global outbreak of the coronavirus that led to the covid-19 pandemic, a team of physicists at Columbia University Irving Medical Center (CUIMC) began exploring whether shorter wavelengths of ultraviolet (UV) light could kill harmful microbes—without harming people. Hospitals had. A novel laser method could enable safe and effective treatment of drug-resistant viruses and bacteria, including HIV and methicillin-resistant Staphylococcus aureus. Although existing laser treatments such as ultraviolet irradiation bypass the problem of drug resistance, such treatments usually. For years scientists have been experimenting with technology for combating viruses with another method — by using a laser, a device which stimulates atoms and molecules to emit light and then amplifies it to create a beam of radiation. In this study, we established standardized UV.
