ripple may damage the product.
4.5 Control Modes
There are two different modes of laser emission: CW and pulsed. In the CW mode, the laser
emits continuously, and you can set the output power by percentage of output power. In the pulse
mode, the laser emits in a waveform of pulses.
We provide three modes to control the product: HyperTerminal, RS-232 and AD. The hyper
terminal mode is a local control mode; RS-232 and AD mode are remote control modes. In the
HyperTerminal mode and RS-232 mode, you can set all the parameters in the CW or pulse mode,
but in the AD mode, the output power is controlled by analog signal, and the emission is
controlled by remote modulation signal.
