Laser light output control apparatus

A laser light output control apparatus for controlling a laser light output from a semiconductor laser, comprising:

• current applying means for applying a driving current to said semiconductor laser based on a given value;
• a microcomputer including
• memory means having a capacity for storing first and second values to be given to said current applying means to set the laser light output at first and second output values, respectively,
• supplying means for supplying said first and second values, respectively, to said memory means to store said first and second values in said memory means, having
• voltage value outputting means for outputting first and second set voltage values, respectively, corresponding to said first and second output values of laser light outputs, and
• counting means for generating an output signal to be given to said current applying means, and
• calculating means for calculating a value to be given to said current applying means for the laser output between said first and second output values from said stored first and second values;
• monitoring means for monitoring a laser light from said semiconductor laser and outputting monitor voltage;
• and
• comparing means for comparing said monitor voltage output of said monitoring means with said first and second set voltage values, respectively, and outputting comparing result signal to be supplied to said counting means to change gradually a value of said output signal of said counting means.
