Abstract
A laser controller (12) that has particular application for controlling a solid state diode laser (10) including a series of gain modules and associated diode arrays. The laser controller (12) includes a control console (44) including a touch screen (46) that allows a laser operator to interface with the controller (12) to control the laser (10) and laser parameters. The control console (44) includes a target monitor (50) that allows the operator to view the laser beam at a reduced beam intensity for alignment and beam quality purposes. The laser controller (12) further includes a computer (14) having a counter circuit (20) that outputs a signal to set the pulse width and pulse rate of the laser beam output. This control allows the laser beam output to be ramped from one beam intensity to another beam intensity during a laser operation. The counter/timer circuit (24) and a series of end of pulse detectors (26) in the controller (12) allow sequencing of the output signal to the various diode arrays in the gain modules so that the laser beam output can be formed into a continuous wave. The computer (14) further includes a pattern generator that outputs a signal that ramps a laser beam modulator to modulate the beam output pulse into a stream of smaller, higher peak energy, pulses. The laser controller (12) also includes a power supply interface system (58) that isolates the control computer (14) from the primary power supplies (16) that provide power to the diode arrays. A laser mirror motor control system (66) allows the operator to manually control the mirrors of the laser (10) through the control console (44). Shut down electronics (70) bypass the computer (14) and automatically shut down the primary power supplies (16) in the event of a safety breach.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
