Divided pulse nonlinear optical sources

An optical system, comprising:

• at least one division stage configured to receive at least one parent pulse and divide the at least one parent pulse into at least two divided pulses;
• and
• at least one nonlinear optical medium configured to receive the at least two divided pulses and generate an output pulse train comprising at least two output pulses;
• wherein the at least one nonlinear optical medium is configured to provide nonlinear parametric gain;
• and
• wherein the at least one nonlinear optical medium behaves as a parametric gain medium for each divided pulse to generate a signal pulse for each divided pulse, an idler pulse for each divided pulse, and a residual pump pulse for each divided pulse.

An optical system, comprising:

• at least one division stage configured to receive at least one parent pulse and divide the at least one parent pulse into at least two divided pulses;
• at least one nonlinear optical medium configured to receive the at least two divided pulses and generate an output pulse train comprising at least two output pulses;
• at least one combination stage configured to receive the output pulse train from the at least one nonlinear optical medium and cause the at least two output pulses of the output pulse train to combine into a combined output pulse;
• and
• an information feedback loop to indicate whether temporal overlapping between the output pulses is occurring when generating the combined output pulse so as to introduce active stabilization.
