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……

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?

Ink colours Pain management Managing patient expectations Minimising risk   Laser/IPL removal of hair, vessel, pigmentation + skin rejuvenation Choosing the correct settings… Understanding the light-tissue interactions The critical importance of… Continue reading Refresher Courses

Laser Tattoo Removal – the important considerations

Laser tattoo removal has been available commercially since we opened the world’s first private clinic to offer this treatment in Glasgow, Scotland in 1989 following our groundbreaking clinical research program in Canniesburn Hospital, Glasgow during the 1980s (see our 1990 publication in the British Journal of Plastic Surgery). We used the Q-switched ruby laser which… Continue reading Laser Tattoo Removal – the important considerations

“Q-switched 532nm laser energy causes significant vascular damage in the capillary plexus – how does this affect laser tattoo removal?”

A new publication just went live on the British Journal of Dermatology site at http://onlinelibrary.wiley.com/wol1/doi/10.1111/bjd.16130/abstract. Full article can be viewed here. It discusses my observations on non-tattooed skin (my own) following irradiation with a Q-switched 532nm laser. I found that there is a significant amount of damage in the capillary plexus soon after irradiation. This… Continue reading “Q-switched 532nm laser energy causes significant vascular damage in the capillary plexus – how does this affect laser tattoo removal?”

Are picosecond lasers worth the cost?

That’s a good question! A picosecond laser costs around £100,000 in the UK, at the moment. A ‘standard’ Q-switched laser costs anywhere between £10,000 and £60,000. QS lasers can output up to 2 Joules of energy in pulsewidths as short as 5 nanoseconds, while some commercially available pico lasers can output up to 1 Joule… Continue reading Are picosecond lasers worth the cost?
