4.5 Work Patterns and Control Modes
There are two work patterns for the laser: CW(continuous wave)and pulse pattern. In CW
pattern, the laser emits continuously, and user can set the output power by percentage of output
power.As for pulse pattern, The output beam oflaser is pulsing, transform the waveform by
setting frequency, duty ratio and the percentage of power.
There are threecontrol modes to choose, external control RS-232 mode, external control AD
mode, and Internal controlmode. RS-232 mode is to set up parameters and control laser enable
signal externally. AD mode is to set up parameters (MOD, Analog Quantity) and control laser
enable signal externally. Internal control mode is to set up parameters and control laser enable
signal internally. Each control modes can be achieved in two work patterns: CW mode, pulse
mode.
