Direct diode laser module for delivering pulsed visible green laser energy

A method for producing pulsed laser energy for an ophthalmic laser treatment system, the laser module comprising:

• receiving parameter information;
• and
• one or more diodes producing pulsed laser energy in a visible green wavelength range based on the parameter information, wherein durations of discrete pulses of the pulsed laser energy are in a range of 50 to 300 microseconds;
• measuring the power of the laser energy and outputting a detected power signal corresponding to the measured power;
• adjusting power of the laser energy based on a comparison of detected power signal to a predetermined power set point based on the parameter information.

A system for delivering pulsed laser energy to an eye of a patient, the system comprising:

• a control module for setting parameters for the delivered pulsed laser energy based on received parameter information and sending control signals based on the parameters;
• a laser module for delivering the pulsed laser energy based on the control signals, wherein the laser module comprises one or more diodes for producing the pulsed laser energy in a visible green wavelength range, and durations of discrete pulses of the pulsed laser energy are in a range of 50 to 300 microseconds;
• an optical package, which is hermetically sealed and defines a chamber containing optical components of the laser module including the one or more diodes and has a lid secured over one or more surfaces of the optical package, enclosing and hermetically sealing the optical components of the laser module;
• and
• a thermoelectric cooler unit for transferring heat generated by the one or more diodes in the optical package away from the optical package.
