The Q driver is a special power supply that drives the Q switching element to work. It applies the corresponding radio frequency signal to the Q switch element according to the external control signal to complete the laser presence or absence control and Q modulation.
5. RF off time (internal modulation state): factory setting 5μs (adjustable: 2-10μs).
6. It has the function of first pulse suppression, which is easy to adjust and has the function of displaying the number of first pulse suppression.
7. Accept TTL level control signals (pen start signal and modulation signal).
8. Has overheating protection.
9. When the load does not match, it can be alarmed by the panel indicator light.
Laser equipment 2: laser
A laser, as its name implies, is a device that emits light.
Principle: Except for free electron lasers, the basic working principles of various lasers are the same. The necessary conditions for laser generation are the inversion of the particle number and the gain that exceeds the loss, so the essential components of the device have excitation (or pump) source and a working medium with a metastable energy level. Excitation is the excitation of the working medium to an excited state after absorbing external energy, creating conditions for realizing and maintaining the population inversion. The excitation methods include optical excitation, electrical excitation, chemical excitation and nuclear energy excitation. The working medium has a metastable energy level so that the stimulated emission dominates, thereby realizing optical amplification. A common component in a laser is also a resonator, but the resonator (see Optical Resonator) is not an essential component. The resonator can make the photons in the cavity have a consistent frequency, phase and running direction, so that the laser has the same frequency, phase and direction. Good directionality and coherence. Moreover, it can shorten the length of the working material very well, and can adjust the mode of the generated laser (ie mode selection) by changing the length of the resonant cavity, so the general laser has a resonant cavity.
Laser equipment 3: galvanometer
Galvo is an excellent vector scanning device. It is a special oscillating motor. The basic principle is that the energized coil generates torque in the magnetic field. However, unlike the rotating motor, the rotor has a reset torque applied by mechanical springs or electronic methods. When the coil is supplied with a certain current and the rotor is deflected to a certain angle, the electromagnetic torque is equal to the restoring torque, so it cannot rotate like an ordinary motor, but can only deflect. The same, so the galvanometer is also called galvanometer scanning galvanometer.
