In many cases premature ejaculation resolves on its own over time without the need for medical treatment. Practicing relaxation techniques or using distraction methods may help you delay ejaculation. For some men, stopping or cutting down on the use of alcohol, tobacco, or illegal drugs may improve their ability to control ejaculation. Some people are asking how to order priligy online? Ok! Here it goes - simply follow this link and get your answer. Among many suggested online pharmacies in online south africa to order priligy online south africa is my favourite. Try it out and know that ordering priligy online is simple. Premature ejaculation is uncontrolled ejaculation either before or shortly after sexual penetration, with minimal sexual stimulation and before the person wishes. It may result in an unsatisfactory sexual experience for both partners. This can increase the anxiety that may contribute to the problem. Premature ejaculation is one of the most common forms of male sexual dysfunction and has probably affected every man at some point in his life.Ethical promotion helps to ensure that healthcare professionals have access to information they need, that patients have access to the medicines they need and that medicines are prescribed and used in a manner that provides the maximum healthcare benefit to patients.

Researchers at South Africa’s Council for Scientific and Industrial Research (CSIR) have developed the world’s first digital laser, and could spur future laser-related innovations.
The team has shown that laser beams can be digitally controlled from within a laser device. Their findings have just been published in Nature Communications.

“This groundbreaking development is further evidence of the great potential we have in scientific innovation – that the world’s first digital laser should come from our country is testimony to the calibre of scientists that South Africa has,” says Minister of Science and Technology, Derek Hanekom.

Laser devices normally consist of mirrors, energy (light) and a casing containing a medium, for example crystal or glass. The medium changes the frequency of the light to create a laser beam with the perfect characteristics for these different applications.

In conventional lasers, the shape of the light that comes out is either not controlled at all, or a single shape is selected by expensive optics. For example, when a medical doctor undertakes surgery, the beam must be appropriate for precision-cutting.

Alternatively, the laser light can be shaped after exiting the laser using a spatial light modulator – a liquid crystal display (LCD) that can be digitally addressed with grey-scale images representing the desired change to the light. The CSIR team has demonstrated for the first time that this can all be done inside the laser.

“Our digital laser uses the LCD as one of its mirrors that is fitted at one end of the laser cavity. Just as with LCD televisions, the LCD inside the laser can be sent pictures to display. When the pictures change on the LCD inside, the properties of the laser beams that exit the device change accordingly,” says Prof Andrew Forbes, leader of the mathematical optics research group.

The researchers have shown that this allows a purely digital control of what comes out of the laser (laser modes) in real-time, hence the name “digital laser”.

“We showed that by sending an appropriate picture to the LCD, any desired laser beam could be created inside the laser device. This is a significant advancement from the traditional approach to laser beam control, which requires costly optics and realignment of the laser device for every beam change. Since this is all done with pictures, the digital laser represents a paradigm shift for laser resonators,” says Forbes.

In a ground-breaking experiment at the CSIR’s laboratories in Pretoria, the team programmed the LCD to play a video of a selection of images representing a variety of desired laser modes. The result was that the laser output changed in real-time from one mode shape to another.

“The dynamic control of laser modes could open up many future applications, from communications to medicine. Our device represents a new way of thinking about laser technology and we see it as a new platform on which future technologies may be built,” says Forbes.

CSIR Researcher Sandile Ngcobo, who conducted the breakthrough experimental work as part of his PhD studies, believes the significance of the research is to demonstrate the ability within the CSIR to lead innovation in this field.

“I believe the digital laser will be a ‘disruptive’ technology. This is technology which may change the status quo and which could create new markets and value networks within the next few years or decade. The research into the digital laser continues. It adds to the CSIR’s strong track record in the development of laser technology in mathematical optics,” says Ngcobo.
