1. A deformable variable radius mirror comprising a deformable face, the deformable face comprising:
an outer surface that is reflective; and
an inner surface that opposes the outer surface, the inner surface comprising steps that are recessed towards the outer surface, wherein
the deformable face defines cooling channels sandwiched between the outer surface and the inner surface,
the deformable face, including the outer surface, the inner surface, and regions between the outer surface and the inner surface that define the cooling channels, is made of the same metal, and
the same metal has an elastic modulus less than or equal to 100 GPa.
