Enabling the Q-Switch does not cause the Vevo LAZR-X laser cart to start firing. It allows the laser to fire
based on a trigger input.
The Vevo LAZR-X laser cart operates by sending a trigger to the Vevo F2 and receiving a delayed trigger
from the Vevo F2. A typical pulse sequence to fire the laser system would involve:
1. Q-Switch: Enable block
2. Trigger Out block
3. Trigger In block
4. Tx/Rx Event block
Once the Vevo F2 receives a trigger signal from the laser as a "Trigger In" signal, it continues onto the
Tx/Rx Event. The "Trigger In" block is setup with a delay (typically 180-200 us), which causes the Vevo F2
to send a "Trigger Out" signal to the laser system and also start to transmit/receive after the specified time.
Set Wavelength
A Set Wavelength block sets the wavelength of the Vevo LAZR-X laser cart.
