4.
The quantum dot laser of claim 1 in which said quantum dots are all the same size.
5.
The quantum dot laser of claim 1 in which said quantum dots are all the same material.
6.
The quantum dot laser of claim 1 in which said quantum dots are all the same material and the same size.
7.
The quantum dot laser of claim 1 in which said pumping source is an optical pumping source.
8.
The quantum dot laser of claim 1 in which said laser is a bulk optic laser.
9.
The quantum dot laser of claim 1 in which said laser includes a cladding surrounding said host material and having a lower refractive index than said host material and said laser is a channel waveguide laser.
10.
The quantum dot laser of claim 9 in which said host material is a polymer.
11.
The quantum dot laser of claim 10 in which said cladding is a polymer.
12.
