1. A laser resonator, comprising:
a gain medium that produces light from pump energy; and
a variable light attenuator configured to receive light and emit either (i) a first light including a continuous series of micropulses, or (ii) a second light including a series of macropulses at spaced time intervals,
wherein a duration of the macropulses and a duration of the spaced time intervals between macropulses are configured such that the first light and the second light heats tissue to a temperature that causes coagulation.
