Here’s a thought… When is the ‘best’ time to fly through space? Given the technology is always advancing, the velocity of space vehicles will tend to increase over time. So, how does this affect journey times in space? Here’s a scenario: Imagine it is the year 2000 and a spacecraft can travel at maximum velocity,… Continue reading Space travel – when???
A bit of fun…. If you treat 10 tattoo patients a day with a Q-switched laser (using a 10 nanosecond pulse width) and each treatment requires, say, 1000 pulses, then the total treatment time is 0.1 milliseconds. This is the actual time you have applied the laser energy! If you operate your laser clinic for… Continue reading How long have you actually treated patients/clients wth lasers?
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 finally managed to list all my publications – medical/laser journals and trade magazines – into one place – My Publications. Feel free to read through and send me comments, questions, arguments etc. I like a good ‘chat’ about this sort of stuff. I am currently working on a number of new reports into… Continue reading All my publications, so far…
As of now I have a new website covering my LPA stuff – laserprotection.net. It also lists all my publications to date – My Publications. Please visit if you are interested in having your laser/IPL facilities checked for compliance etc. If you need any advice on your laser/IPL equipment please let me know. Mike.
A simple mistake…. I’ve just been contacted by a lady with eye problems. She couldn’t find her usual laser safety glasses and was about to treat some nail fungus So she used her IPL glasses “because they offered protection between 200 and 2000nm”. She used a QS laser at 1064nm followed by a second… Continue reading Eye safety!!
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……
