1. A medical observation system for observing a biological object, the system comprising:
a medical light source apparatus for illuminating the biological object, the medical light source apparatus including
a first laser light source configured to emit a first laser light beam,
a second laser light source configured to emit a second laser light beam having a wavelength band different from a wavelength band of the first laser light beam,
a first optical assembly including a reflecting surface disposed to reflect the first laser light beam, cause the second laser light beam to be transmitted therethrough, and guide the first laser light beam and the second laser light beam in a same direction and produce first output light that illuminates the biological object, and
a first reflection mirror having a reflecting surface that is not parallel with the reflecting surface of the first optical assembly and configured to reflect the second laser light beam to cause the second laser light beam to enter the first optical assembly, wherein the first laser light source, the second laser light source, the first optical assembly, and the first reflection mirror form a first group;
a third laser light source configured to emit a third laser light beam,
a fourth laser light source configured to emit a fourth laser light beam having a wavelength band different from a wavelength band of the third laser light beam,
a second optical assembly including a reflecting surface and disposed to reflect the third laser light beam, cause the fourth laser light beam to be transmitted therethrough, guide the third laser light beam and the fourth laser light beam in a same direction, and produce a second output light that illuminates the biological object;
a second reflection mirror having a reflecting surface that is not parallel with the reflecting surface of the second optical assembly and configured to reflect the fourth laser light beam to cause the fourth laser light beam to enter the second optical assembly, wherein the third laser light source, the fourth laser light source, the second optical assembly, and the second reflection mirror form a second group;
a condenser lens that receives the first output light from the first group and the second output light from the second group and condenses the received light; and
a medical observation device including a detector for detecting a light received from the biological object.
