Moku Laser Lock Box has output voltage limiters designed for exactly this purpose. You can set arbitrary high and low limits on each output and the control signals will be clamped to these levels, preventing damage to sensitive actuators. For example, in the screenshot below, the limits block is configured with a high limit of 1 Volt and a low limit of 0 Volts. As a result, the output signal contains only the positive segments.
Note that the modulation signal from the auxiliary oscillator is not clamped to avoid clipping and distortion.
