Answer #1

Q1)option 5 is false as Nad:yag and CO2 laser is used in treatment of cornea.The erbium provides the laser activity in the crystal. Er:YAG lasers typically emit light with a wavelength of 2940 nm, which is infrared light. Unlike Nd:YAG laser, the output of an Er:YAG laser is strongly absorbed by water.

So instead of er:yag here nad:yag is used.

According to the HOMEWORKLIB RULES I am bound to do only first question in case of multiple questions.if you want any specific question then please mark that one

Sorry for inconvenience.
