Abstract

Embodiments of methods and systems for distributing laser energy are disclosed herein. A system for dispensing laser energy by one or more laser energy sources in accordance with one embodiment of the present technology includes a laser energy credit transferring component configured to communicate with a laser energy source. The laser energy source is configured for producing and dispensing laser energy. The laser energy credit transferring component is further configured to receive a request from the laser energy source for laser energy and transfer laser energy credits to the laser energy source. The laser energy credits enable the laser energy source to dispense a corresponding amount of laser energy.

Claims

1. A system for dispensing laser energy by one or more laser energy sources, the system comprising:

a laser energy credit transferring component configured to—

communicate with a laser energy source, wherein the laser energy source is configured for producing and dispensing laser energy;

receive a request from the laser energy source for laser energy; and

transfer laser energy credits to the laser energy source, wherein the laser energy credits enable—

the laser energy source to dispense a corresponding amount of laser energy to provide a laser beam for processing materials via a material processor, and

a user of the material processor to directly control a rate at which the laser energy source dispenses the laser energy to provide the laser beam.

2. The system of claim 1 wherein the laser energy credit transferring component is further configured to:

determine the validity of the request; and

transfer the laser energy credits when the request is valid.

3. The system of claim 1 wherein:

the laser energy source has a laser energy credit cutoff threshold below which the laser energy source is inhibited from dispensing laser energy; and

the laser energy credit transferring component is further configured to receive the request when the laser source has reached the laser energy credit cutoff threshold.

4. The system of claim 3 wherein the laser energy cutoff threshold is zero laser energy credits.

5. The system of claim 3 wherein the laser energy cutoff threshold is a negative amount of laser energy credit.

6. The system of claim 1, further comprising a laser energy tracking component configured to monitor the laser energy dispensed by the laser energy source.

7. The system of claim 6 wherein the laser energy tracking component is further configured to:

monitor at least one of the following of the laser source—

a portion of dispensed laser energy, wherein the dispensed portion of laser energy is related to a total amount of dispensed laser energy;

electrical current, wherein the electrical current corresponds to an amount of dispensed laser energy;

the cumulative time of emission of laser energy multiplied by nominal power of the laser energy source; and

correlate at least one of the portion of dispensed laser energy, electrical current, and/or sum of individual dispensed laser energy pulses to determine a corresponding amount of consumed laser energy credits.

8. The system of claim 1, further comprising the laser energy source.

9. The system of claim 8, further comprising the material processor.

10. The system of claim 1 wherein the rate at which the laser energy is dispensed is based at least in part on a cumulative on time of the laser source multiplied by a nominal output power rating of the laser source.

11. The system of claim 1 wherein the rate at which the laser energy is dispensed is based at least in part on a cumulative on time of the laser source.

12. The system of claim 1 where the laser source is one of a plurality of laser sources each having a different nominal power rating than the other, and the wherein the rate at which the laser energy is dispensed is based at least in part on a cumulative on time of each of the laser sources.

13. The system of claim 1 wherein at least a portion of the laser energy credit transferring component is located at a facility of a laser energy credit provider remote from the laser energy source.

14. A system for dispensing laser energy by one or more laser energy sources, the system comprising:

a laser energy source configured for producing and dispensing laser energy to provide a laser beam to a material processor for processing materials via the laser beam; and

a laser energy credit transferring component at a facility remote from the laser energy source, wherein the laser energy credit transferring component is configured to—

communicate with the laser energy source, and

transfer laser energy credits to the laser energy source, wherein the laser energy credits enable the laser energy source to dispense a corresponding amount of laser energy for forming the laser beam.

15. The system of claim 14 wherein the laser energy credit transferring component is further configured to receive a request from the laser energy source for the laser energy.

16. The system of claim 14 wherein the laser energy transferring component is associated with a vendor of the laser energy source.

17. The system of claim 14 wherein a user of the material processor is enabled to directly control a rate at which the laser energy source dispenses the laser energy to provide the laser beam.
