What is the pulse rate of a laser?
What is the pulse rate of a laser?
Typical mode-locked solid-state lasers emit with pulse repetition rates between 50 MHz and a few gigahertz, but in extreme cases < 10 MHz or > 100 GHz are possible.
How is laser pulse calculated?
For a pulsed laser, you will need to divide the average power of your source by its repetition rate. Laser specification sheets usually give these two parameters, but for a better accuracy, they can also be measured by suitable instruments.
What is laser repetition rate?
Solid-state lasers pumped by flashlamps present pulse repetition rates typically in the range 10–20 Hz. This repetition rate is suitable for use in LIBS systems aimed at the determination of bulk concentrations of the elements in a sample.
How many pulses do you need for laser hair removal?
As a rough guide, the approximate number of pulses necessary to treat the following areas of the body are: upper lip: 25 pulses. underarm: 100 pulses. bikini line: 200 pulses.
What is pulse time?
Pulse-on time or pulse duration: The time interval during which the spark (electron discharge) occurs between electrode (wire) and the workpiece once the break down voltage of the dielectric is reached causing its ionization. Consequently the spark then causes erosion of the workpiece material.
What is laser duty cycle?
Duty Cycle Range (A percentage of laser on time) • Duty cycle is the percent of laser on time in a given command signal. (e.g.: 50\% duty cycle means the laser is firing half the cycle time and off the other half). • CW lasers are assumed to have a duty cycle range up to 100\%, or continuously on.
What is pulse repetition time?
The pulse repetition interval (PRI) is the time interval between pulses. If the next pulse was transmitted before this interval the radar receiver would not be able to decide whether a return was from a long range target illuminated by the preceding pulse or a short range target from the subsequent pulse.
What is pulse width duration?
From Wikipedia, the free encyclopedia. The pulse width is a measure of the elapsed time between the leading and trailing edges of a single pulse of energy. The measure is typically used with electrical signals and is widely used in the fields of radar and power supplies.
Is 6 sessions of laser hair removal enough?
To ensure effective laser hair removal and achieve the best results, we advise that you go for six sessions at first and add two additional sessions after the end of your initial treatment.
