The diode head should not normally be disconnected from the driver board (the diode is very sensitive to static and any accumulated charge in the power supply). Power should be supplied via the red and black cables. The green socket gives optional TTL control (connect the wires together to blank the laser). TTL modulated driver box will support an additional red laser head (not supplied)

The laser is very stable. cooling is very good so has no problems in continuous operation. TTL circuit gives the required output.
