Final answer:
The C. Argon laser is the one with blue-green light that is highly absorbed by hemoglobin and is used through a fiber system, different from the CO2 and YAG lasers which serve different purposes in medical applications.
Step-by-step explanation:
The laser with blue-green light that is highly absorbed by hemoglobin and delivered through a fiber system is the C. Argon laser.
This type of laser has the ability to target specific components in the blood due to its unique wavelength which is well-absorbed by hemoglobin.
In contrast, a carbon dioxide (CO2) laser emits infrared radiation with a wavelength of 10.6 µm and is typically used for cutting or evaporating tissue due to its high water absorption characteristics.
A YAG laser uses a solid crystal as the lasing medium and is often employed for a variety of applications, but does not typically emit in the blue-green part of the spectrum and is not known for being highly absorbed by hemoglobin.
