CAUTION
：
Please check the control voltage level and ensure
that the level is in accordance with the requirements. Over
voltage and voltage ripple may damage the product.

Operation Mode and Control
There are two different modes of operation-CW and modulation. In the CW
mode, the laser emits continuously, and you can set the output power by
percentage of output power. In the modulation mode, the laser emits in a waveform
of pulses. The pulse can be set by the frequency, duty cycle and power percentage.
Laser power can be set in two ways: by communicating commands through a
the serial port or by setting analog voltage through an external AD mode. At the
same time, there are two ways of laser optical control: communication command
through serial port or MODULATION signal control through the control interface.

Entering a Control Mode
The Figure 14 shows the process of entering a control mode.
