There is a curious anomaly around today. When we discuss our weight we invariably refer to the number of kilograms we ‘weigh’. But this is a measurement of mass, not weight! So, if someone claim a weight of 100 kg, they are really referring to their mass. This is where it gets interesting. To… Continue reading What is your weight on Mars? Or other planets???
I have a new training course available now, due to demand! If you are interested in the treatment of onychomycosis (nail fungus) using a Q-switched Nd:YAG laser then contact me. I have reviewed the current literature and composed an effective clinical protocol around the evidence. Nail fungus can be treated very well with QS… Continue reading New Training Course – Onychomycosis
We are ALL time-travellers. According to Einstein we move thru spacetime, not time. One day at a time…. Personally, I cannot see how time travel is possible. Nor is it sensible. Being able to go back in time and change something is just a fantastically stupid concept as to be non-sensical. Why would… Continue reading Time Travel – is it possible?
I’ve just received acknowledgement that my paper – High speed ink aggregates are ejected from tattoos during Q‐switched Nd:YAG laser treatments has been accepted for publication in Lasers in Surgery and Medicine. It should be available for public consumption next month, but if you want a wee preview just let me know. Mike.
I can now offer the following ‘refresher courses’: Laser tattoo removal: Choosing the correct settings Which laser is best? How does it actually work? Ink colours Pain management Managing patient expectations Minimising risk Laser/IPL removal of hair, vessel, pigmentation + skin rejuvenation Choosing the correct settings… Understanding the light-tissue interactions The critical importance of… Continue reading Refresher Courses
Throughout the last few years I have heard some people (usually sales people) trying to bamboozle potential customers with various nonsense claims. This is to be expected I suppose, but one which does irritate me greatly is the ‘active’ vs ‘passive’ Q-switch debate!! So, I thought I’d write a wee piece about this topic,… Continue reading Q-switches: Passive vs Active?
Well, this is a very interesting question…. From a ‘classical’ viewpoint (i.e. the world in which we live) this is easily calculated by multiplying the speed of light, c, with the laser pulse duration. So, for a Q-switched Nd:YAG laser of, say, 5 nanosecond duration, the laser pulse is approx. 1.49 metres long, while a… Continue reading How long is a beam of laser light?
