A brief history of my life in medical lasers and IPLs…
Laser energy, energy density, fluence, leprechauns and star bursts……
I constantly hear laser users talking about the ‘energy’ they are using to treat tattoos, hair, blood vessels etc. However, it is clear that many don’t really understand what they mean. I often read about treatments using “500” or “250” or “never above 600” joules, millijoules or whatever!! I think these are the numbers… Continue reading Laser energy, energy density, fluence, leprechauns and star bursts……
My articles – …
I have updated my published articles – both in peer-reviewed journals and in trade magazines. You can find them here…. Let me know what you think please. Cheers, Mike.
What is your weight on Mars? Or other planets???
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???
New Training Course – Onychomycosis
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
Single or Double Rod Nd:YAG Lasers?
Nowadays, it is possible to purchase Q-switched Nd:YAG lasers with a single YAG rod, or with two rods. So, what is the difference and is it important? To understand why a laser might have two rods instead of one we should look at the basic design of a laser first. Basic laser cavity A… Continue reading Single or Double Rod Nd:YAG Lasers?
Do your eyes hurt after ‘lasering’?
Three times in three weeks I’ve heard the same comment – “my eyes hurt for a few hours after I’ve finished lasering”….. All three times that has raised alarm bells in my head. As a Laser Protection Adviser I knew right away what this meant. It means that their eyes were not being properly… Continue reading Do your eyes hurt after ‘lasering’?
Time Travel – is it possible?
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?
