Most laser systems have a lens to focus the laser energy down to a sale spot diameter (see figure 1 below). However, in many systems, the focal point (where the spot diameter is the smallest) is outside the handpiece assembly. This has a potentially hazardous effect if not properly understood! The problem with this design… Continue reading Laser spot size – how it changes with distance from the target…
IPL systems typically use a Xenon flash lamp to generate light across a wide range of wavelengths, usually 400 to 1200 nm. To select a ‘useful’ range a filter is applied. These are generally ‘cut off’ filters which stop all wavelengths below a given value, from transmitting through. Hence, a 650 nm will stop all… Continue reading IPL filters
Recently I tried the new ‘carbon facial’ treatment using the 1064nm wavelength of the Q-switched Nd:YAG laser. My wife was keen to try it! I painted a little black carbon ink solution (which I made myself) onto my wife’s face. After about 20 minutes, or so, to allow it to dry, I applied the laser… Continue reading Carbon Facial treatment with a QS Nd:YAG laser
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 wrote an article for Aesthetics recently regarding the plume generated by laser/IPL hair removal and other treatments. All ablative treatments will generate a plume. In addition, many other laser/IPL treatment will also generate plume. What is a ‘plume’? Plume consists of smoke particles and tiny, invisible particles of tissue, hair, bacteria, viruses and potentially… Continue reading Laser/IPL Hair Removal – plume and precautions!!!

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
