The invention relates to a
laser output
power optimization method based on a variable-
transmittance endoscope, and belongs to the technical field of
laser. The method comprises the following specific steps: (1) calculating the output power of a needed pump source according to the requirement of the design index on the
laser output characteristic; (2) calculating the optimal
transmittance values under different pump power according to the range of pump power and the optimal
transmittance formula; (3) determining the
coating requirement of the variable-transmittance
endoscope according to the tuning characteristics of the oscillation
wavelength of a laser; (4) making the variable-transmittance
endoscope according to the
coating requirement; (5) adopting the selected pump source and the variable-transmittance endoscope to build a laser
system; (6) setting the pump power, and adjusting a laser
resonator to obtain laser output; (7) tuning the laser
wavelength; and (8) making the laser work stably at the optimal transmittance to obtain the maximum output power, thus completing
online optimization of the output power of the laser. According to the invention, there is no need to insert elements into the cavity, and the loss is low. The optimization method is simple, reliable in work, convenient in operation, and wide in adaptability.
