Checking for the patency of transmission is crucial as the first step when preparing to use a diode laser. This process ensures that all components necessary for the laser to function — including the fiber optics or any light delivery system — are unobstructed and in good working condition. If the transmission pathway is blocked or damaged, it can lead to ineffective treatment, potential injury to the patient, or damage to the equipment.

Before proceeding with calibration, anesthesia application, or adjusting energy levels, confirming that the laser's output can effectively reach the intended tissue is a priority. This proactive step helps prevent complications and ensures that subsequent actions, such as calibrating the laser or setting energy levels, are done with confidence that the system is fully operational.
