How do you calibrate your lasers so that the numbers on your laser screen actually mean something useful? Well, there is a process which you need to follow. The video shows this process in detail. So, you need to measure the laser energy for each of your ‘input’ settings using an energy meter designed for… Continue reading Calibrating your laser – making sense of the numbers…
I have been asked many times in the last few years for a recommendation for an introductory book describing the application of lasers and IPLs in aesthetic treatments. My answer was always the same – “There isn’t one!!” So, I finally took the plunge and decided to write one, with my colleague PA Torstensson. The… Continue reading New Book – Medical/Aesthetic Lasers & IPLs and Skin Treatments
I recently read an excellent article entitled “Effects of picosecond laser on the multi-colored tattoo removal using Hartley guinea pig: A preliminary study” by some researchers in South Korea. You can obtain a copy here. In it, they compare the use of two picosecond lasers and a nanosecond Nd:YAG laser. In all, they use three… Continue reading Picosecond vs Nanosecond Laser Tattoo Removal: which is better?
‘Q-switched ruby laser treatment of tattoos: a 9 year experience’ – British Journal of Plastic Surgery (1990), 43, 663-669.‘ I can’t believe we wrote this paper 30 years ago!!! I am still working on this topic. In particular, I am modeling the interactions between laser energy and tattoo ink particles, with both nano- and… Continue reading My first published paper…. on laser tattoo removal, in 1990
Finally, I’ve caught up with Zoom! I can now offer my training courses online in a one-to-one situation. You can ask me questions during the course whenever you like. Plus, you don’t need to have Zoom on your computer!! I prefer to do these courses with a small group of people – no more… Continue reading One-to-one online training now available
New Paper – click here I just had a new paper published in the journal ‘Lasers in Medical Science’. It discusses the amount of back-scatter light emanating from the skin during laser treatments. It is much higher than we had previously thought. This comes from new Monte Carlo modeling which found that back-scattering is much… Continue reading New paper – my musings on back-scattered laser light from tattoo treatments
I have just built a new website for my training stuff – at dermalase-training.com. Go and have a wee look around please. Let me know any comments you may have… Cheers, Mike.

I’ll be presenting OP18 and OP20 on Friday May 10th, 2019 at 8.15am and 8.45am respectively, in the Endeavour Room. 1st Presentation – OP18 The first presentation is entitled “Laser Tattoo Removal – a deeper analysis… Continue reading British Medical Laser Association annual meeting 2019 – My talks
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……
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?
