The default cycle for pulse mode is to have the phaco energy on and then off for equal periods (50:50), thus giving a duty cycle of 50%.

In other words, the duty cycle of the output pulse is 50%. By evaluating the equation for T H, you get 11.4 nsec. Thus, The circuit’s output frequency is 56.75 MHz with a power-supply voltage of ...

Previously-known schemes for RC rectangular pulse generators with a regulated duty cycle had an ineradicable disadvantage: changing the pulse fill factor (D) inevitably changed the frequency of ...

GIGAPHOTON announced today that it has successfully achieved continuous operation of 140W EUV light source at 50 percent duty cycle.

Pulse programming with variable duty cycle modifies energy delivery Varying the duty cycle can help deliver less phaco energy into the eye, resulting in better outcomes.
