- the term “substantially” means that the diameter of the light beam is expanded and the entire surface is irradiated simultaneously, and the light beam with a small diameter is irradiated while scanning the liquid surface. It means that the total light energy expressed by power X irradiation time X irradiation area becomes equal. In the fast filling process, the time allotted for the defoaming process Therefore, a sufficient defoaming effect cannot be obtained with the intensity of light emitted from a normal light source. Conversely, in order to input sufficient energy to obtain a defoaming effect, a light source with a great deal of power is required, which is not practical.
- the wavelength of the ultrasonic wave is the size of the target container.
- the efficiency is inferior because it has the same degree, lacks directivity and dissipates the irradiation energy. Therefore, it is necessary to perform defoaming while running a long distance on the competitor, which is not preferable from the viewpoint of space saving because the production line becomes long.
- the conventional method has a problem in that the foam adhering to the inner peripheral surface of the container can hardly be eliminated.

Therefore, unlike the case of defoaming by light irradiation such as a conventional laser beam, it is not necessary to irradiate each bubble with a beam, so that defoaming can be performed at high speed in a short time. Further, since the pulse-like sound wave propagates to the inner peripheral surface of the container, the bubbles near the inner peripheral wall surface of the container, which has been difficult to defoam by the conventional method, can be effectively defoamed.

It is installed above the container passage position before sealing, and irradiates the liquid surface of the container passing therethrough with pulsed light.
- a pulse laser that can release the energy stored in the laser medium until a certain moment as an optical pulse at a stroke is suitable.
- pulse lasers femtosecond lasers such as YAG laser, YVO laser, YLF laser, and titanium sapphire laser capable of Q-switch oscillation are available.
- pulse lasers have a repetition rate of several Hz to several tens of kHz.
- the energy stored during this repetition cycle is emitted in a very short time span of several femtoseconds (fs) to several tens of nanoseconds (ns). To do. Therefore, high peak power can be obtained efficiently from low input energy.

- harmonic light generated by a wavelength conversion element from the fundamental wave of these laser light sources can also be used.
- These light sources include a continuous wave (CW) light source.

- the condensing optical system when used, the optical power density per unit area can be sufficiently reduced except for the beam waist where the light is most concentrated. This can also avoid danger to the human body that does not cause damage even if light hits parts other than the irradiation target, such as the container wall surface, top surface, and peripheral devices.
- the sound wave When the intensity of the impact pressure pulse is large, the sound wave propagates as a shock wave. In this case, a higher bubble breaking effect can be obtained. Since the pulsed sound wave generated in this way propagates as a spherical wave with the irradiation point as the sound source, it can exert a bubble-breaking action on bubbles that exist outside the light propagation path. An efficient defoaming effect is obtained.
- the light collecting point is collected. 12 can cause an air breakdown phenomenon in the light propagation path. This also makes it possible to generate pulsed sound waves. Such a breakdown caused by collecting the lasers is called laser induced breakdown (LIB).
- LIB laser induced breakdown

- the stable optical system since the oscillating light is a multimode in which many modes are mixed, the wavefront is not uniform and the light collecting property is relatively inferior, so the LIB generation efficiency is relatively low. Requires more power.
