Origin of Spanish Green Laser Diodes
The active region of the laser diode is in the intrinsic (I) region, and the carriers (electrons and holes) are pumped into that region from the N and P regions respectively.

Can laser diodes treat viruses
Different studies reported that photobiomodulation therapy (PBMT), employing laser light at various wavelengths can counteract viral infections. Laser light in the red range has been described as an effective tool to fight herpes simplex virus type 1 (HSV‐1) in infected patients. This work describes a laser device able to rapidly sterilize aerosol containing infectious viruses and bacteria, including Legionella pneumophila and SARS-CoV-2, when aerosolized by a novel system able to mimic droplet formation during human speech. 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. 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. The findings could lead to new ways to sterilize wounds and blood products without damaging human cells.

How to increase the power of laser diodes
Modulating the output power of a laser diode can happen in two ways: by changing the signal input/driving current1,2 or by alternating the continuous wave output after the light is generated. 2 In laser modulation, the current or voltage varies with time to modulate the output. Although I didn't find anything that exactly matching my specifications, I did find this from Thorlabs and this from Roithner Lasertechnik.

Are laser lights diodes
The laser diode is a form of semiconductor diode that generates coherent laser light rather than the more usual incoherent light produced by other sources such as LEDs or other emitters, even though some of these produce a narrow band of frequencies. A laser diode (LD, also injection laser diode or ILD or semiconductor laser or diode laser) is a semiconductor device similar to a light-emitting diode in which a diode pumped directly with electrical current can create lasing conditions at the diode's junction. It works on the same basic principle as an LED, but with an internal structure that forces photons to align in phase and direction, producing coherent laser light instead of the. They consist of a p-n semiconductor junction, with a forward bias voltage applied. So what's the difference between LED and Laser diodes? Let's find out the details. Operational Mechanism: Laser diodes create light through stimulated emission within an optical cavity, with the light's properties influenced by the semiconductor. These gadgets track down wide applications because of their proficiency and minimal size.
