CLAIMS

What is claimed:

1. A method for upgrading a countermeasure laser system comprising the steps of:

removing a legacy single laser system in the form of a first line replaceable unit (LRU) from a countermeasure system on a vehicle;

providing a hybrid laser countermeasure system in the form of a second LRU including at least two generable laser beams, wherein a generable first laser beam is a pulsed laser beam and a generable second laser beam is a continuous wave (CW) laser beam;

installing the second LRU into the countermeasure system on the vehicle, wherein the second LRU is adapted to disable an incoming threat to the vehicle; and

connecting the second LRU to a legacy power source and a legacy modulation source on the vehicle.

2. The method of Claim 1 , further comprising the step of:

generating the first laser beam; and

generating the second laser beam.

3. The method of Claim 2, further comprising the step of temporally combining the first and second laser beams via combining logic to create a combined laser beam having a customized waveform.

4. The method of Claim 3, wherein the step of combining the first and second laser beams via combining logic to create the combined laser beam having the customized waveform is accomplished by one of the following:

(a) spectral beam combining with a grating;

(b) spectral beam combining with free space optics utilizing N-chroic optical coatings;

(c) polarization combining; and

(d) spatial combining utilizing one or more of mirrors, lenses, optical fibers, or a combination thereof.

5. The method of Claim 4, further comprising the steps of:

targeting the combined laser beam at an optical guidance system on an incoming threat to the vehicle; and

disabling the threat with the combined laser beam.

6. The method of Claim 2, wherein the step of generating the first laser beam is accomplished by energizing a single gain medium inside the second LRU and the step of generating the second laser beam is accomplished by energizing said single gain medium.

7. The method of Claim 2, wherein the step of generating the first laser beam is accomplished by energizing a first gain medium inside the second LRU and the step of generating the second laser beam is accomplished by energizing a second gain medium inside the second LRU.

8. The method of Claim 1 , wherein the step of connecting the second LRU to the legacy power source and the legacy modulation source on the vehicle is accomplished by connecting existing hardware connections on the vehicle with the second LRU that were previously connected to the first LRU.

9. The method of Claim 8, further comprising the steps of:

generating the first laser beam with power from the legacy power source external the second LRU;

modulating the first laser beam with modulation signals from the legacy modulation source external the second LRU; and

generating the second laser beam with power from the legacy power source.

10. A hybrid laser countermeasure line replaceable unit including:

a housing defining an internal cavity and a laser beam exit aperture;

a transparent lens at the laser beam exit aperture enabling passage of electromagnetic radiation therethrough;

a first laser beam generated from within the internal cavity and the first laser beam exiting the laser beam exit aperture, wherein the first laser beam is a pulsed laser beam; and

a second laser beam generated from within the internal cavity and exiting the laser beam exit aperture, wherein the second laser beam is a continuous wave (CW) laser beam;

wherein the hybrid laser countermeasure line replaceable unit is adapted to replace a legacy single laser unit from a countermeasure system on a vehicle and disable optically guided incoming threats.

11. The hybrid laser countermeasure line replaceable unit of Claim 10, further comprising:

a single gain medium disposed within the internal cavity generating both the first laser beam and the second laser beam.

12. The hybrid laser countermeasure line replaceable unit of Claim 11 , further comprising:

a combined laser beam passing through the exit aperture formed from the first and second laser beams combined together in combining logic operatively coupled with the single gain medium.

13. The hybrid laser countermeasure line replaceable unit of Claim 12, further comprising:

a modulation source external the housing and part of a legacy countermeasure system on the vehicle, the modulation source operatively coupled to control logic to the control modulation pulses associated with the first laser beam.

14. The hybrid laser countermeasure line replaceable unit of Claim 13, wherein the control logic is carried by the housing.

15. The hybrid laser countermeasure line replaceable unit of Claim 14, wherein the control logic manages generation of the first and second beams in the single gain medium synchronously.

16. The hybrid laser countermeasure line replaceable unit of Claim 14, wherein the control logic manages generation of the first and second beams in the single gain medium independently.

17. The hybrid laser countermeasure line replaceable unit of Claim 10, further comprising:

a first gain medium disposed within the internal cavity generating the first laser beam; and

a second gain medium disposed within the internal cavity generating the second laser beam.

18. The hybrid laser countermeasure line replaceable unit of Claim 17, further comprising:
