    Abstract: A single loop hardware-based system for producing laser pulses in a microsecond scale operational mode includes a GUI to enable a user to select the operational mode of the system; a laser source for producing one or more laser beam pulses, the laser source being a diode laser pump source module; a DSP which enables and disables a hardware-based FPGA. The FPGA controls the diode pump source module. When a user selects one or more microsecond scale laser sub-pulses on the GUI, the DSP transmits to the FPGA the sub-pulse energy level and the sub-pulse on-time selected by the user on the GUI. A photodetector operatively connected to the hardware-based system measures the power of the laser pulse beam that was transmitted to the photodetector and, in a feedback mode, transmits a feedback signal of that power measurement to the FPGA. The FPGA compares the power of the laser beam measured by the photodetector to the power of the laser beam selected by the user on the GUI. If the power level read by the FPGA is higher than the selected power level, the FGPA decreases the power level to the pumping source module for any subsequent laser pulses; and if the power level read by the FPGA is less than the selected power level, the FGPA increases the power level to the pumping source module for subsequent laser pulses.

    Abstract: A method of treating ophthalmic tissues of the body by the application of multiple laser pulses on each single spot intended to be treated while reducing heating of the ophthalmic tissues includes providing a source of pulsed laser energy movable in X and Y dimensions; determining the location and dimensions of the area of the ophthalmic tissue to be treated; determining an array of X rows by Y columns target spot positions within the area to be treated; then firing a single pulse of the source of laser energy at an initial target spot in the first of the X rows; firing a single second spot of laser energy at the next adjacent target spot along the first of the X rows and repeating the sequence until treatment is completed. A continuous wave (CW) laser energy source may also be utilized in practicing the method by moving the CW laser energy source in a determined pattern.
