1. A method providing a laser output, the method comprising:
providing a first laser input with a first average power from a first pump laser source;
providing a second laser input at a first state with a second average power from a second pump laser source;
generating a first laser output using a crystal to provide conversion of the first laser input with the first average power and the second laser input at the first state with the second average power using difference frequency generation (DFG);
after generating the first laser output, providing the second laser input at a second state with the second average power from the second pump laser source, wherein the first and second states of the second laser input are different, and wherein the second average power remains unchanged for the first and second states of the second laser input, and wherein a combined power of the first laser input and the second laser input at the first state is the same as a combined power of the first laser input and the second laser input at the second state; and
after generating the first laser output, generating a second laser output using the crystal to provide conversion of the first laser input with the first average power and the second laser input at the second state with the second average power using DFG, and wherein powers of the of the first and second laser outputs are different.
