... A range of voltages may appear across the tetrode, depending on the power supplied to the laser and the need to retain non-oscillating conditions in the circuit. This may make neces- sary the use of sophisticated averaging of anode dissipation, or alternatively the use of con- servative ratings. 2. Grid Impulse amplitude= grid voltage - grid bias voltage.
