1. An endoscopic light source comprising:
an ingress laser source comprising a first laser driver unit configured to produce a first beam that results in a plasma sustaining beam and a second laser driver unit configured to produce a second beam that results in a visible beam, wherein the second beam is mixed with the first beam to produce an output beam;
a lamp comprising:
an ingress window configured to receive an inlet beam based on the output beam of the ingress laser source,
a sealed chamber storing ionizable medium that, once ignited by the inlet beam, forms a high intensity light emitting plasma, and
an egress window configured to emit a high intensity light produced by the high intensity light emitting plasma; and
an exit fiber having a diameter that is less than 500 micrometers, the exit fiber configured to receive and convey the high intensity light.
