Low power laser now is very useful in medicine in general and in microbiology in particular.It can kill bugs infecting our body but how depth can penetrate to eradicate pathogens?

The exact penetration depth of LLLT in human tissue remains unspecified.
Some literature suggest that the depth of penetration of laser radiation using wavelengths from 630nm up to 1100nm may be up to 50mm and some study supporting that most laser radiation absorbed within the first 1mm of skin.

Sir,
The depth of penetration depends on wavelength and power of LASER. i have enclosed a interesting article for your reference.

I hope this figure which shows the wavelength dependency of the penetration depth of different lasers also helps.
and more specifically the wavelength dependency in the visible region:
