My first ever publication! That was a long time ago when I was just a lad… Me! As a lad… We published this article in the British Journal of Plastic Surgery (our boss was a plastic surgeon!) to tell the world about our clinical work of 9 years which clearly showed that the ruby… Continue reading Q-switched Ruby Laser Treatment of Tattoos – a 9 year Experience : published in 1990
Article This article discusses our take on TRTs in a (relatively) non-mathematical way. It discusses tissue denaturation using the Arrhenius Damage Equation which describes the ‘change of state of one species into another’. It also introduces the concept of ‘Omega’ – a parameter which describes the amount of tissue damaged by the heating process. I… Continue reading “Thermal Relaxation Times” – Body Language magazine
Article This is an article I co-authored with my good friend, PA Torstensson, about our interpretation of the idea that thermal relaxation times (TRTs) can be used to determine the pulse duration of laser energy when applied to skin conditions (hair, blood vessels etc). We disagree with this idea – as the title hints at!… Continue reading “Thermal relaxation times: an outdated concept in photothermal treatments”
Another wee rant about the state of the industry and the garbage that some manufacturers sell to unsuspecting customers!!!! PDF version Cosmetic News version – page 41 Mike. email@example.com
I wrote this article a few years ago after people kept asking me what the difference was between CE marked systems and FDA ‘approved’ systems. PDF version Cosmetic News version – page 22 Mike. firstname.lastname@example.org
Here is an article I wrote about the lack of meters to check the energy output of IPL systems. It’s a bit of a moan, to be honest! PDF version Cosmetic News version – page 44 Mike. email@example.com

Have you ever wondered how many photons you generate each time you fire a pulse of laser energy? I have! Fortunately, I can work it out because I’m a physicist. It’s the kind of thing us physicists do!! It keeps us off the streets at night…… So, to calculate this number we need to… Continue reading How many photons are in a laser pulse?
Have you ever wondered how bright your laser is? Given that it outputs millions of watts of light (in both 1064 and 532nm) you might imagine that it is quite bright…. Well I took a couple of videos to see for myself. Our laser safety glasses are rated at OD7 – that means if 10… Continue reading How bright is your Q-switched Nd:YAG laser?
Just thought I’d post some photos which I took earlier to view the brightness of the 532nm wavelength compared with the 1064nm line on a tattoo… Note: all photos and videos were taken using an iPhone 6. The top photo shows the tattoo just before the laser is fired at 1064 nm. The… Continue reading 532nm treatment of a tattoo – what does it actually look like?
