1. A system comprising:
a plurality of laser sources, wherein a first laser source of the plurality of laser sources is configured to emit light having a first wavelength range and a second laser source of the plurality of laser sources is configured to emit light having a second wavelength range different from the first wavelength range to an in vivo target site;
an endoscope having a proximal portion and a distal portion, the distal portion being configured to be inserted into a location in proximity to the in vivo target site;
a controller configured to:
analyze a first signal from the in vivo target site to determine a first depth at the in vivo target site, wherein the first depth relates to a first penetration depth of first emitted light into the in vivo target site; and
based at least in part on the first depth at the in vivo target site, selectively activate the first laser source so as to treat the in vivo target site; and
wherein the controller is further configured to:
 receive a second signal from the in vivo target site;
 analyze the second signal to determine a second depth at the in vivo target site, wherein the second depth relates to a second penetration depth of second emitted light into the in vivo target site; and
 based at least in part on the second depth of the in vivo target site, selectively activate the second laser source so as to adjust a treatment effect at the in vivo target site.
