As many of you know, I keep banging on about eye safety when working with lasers. Many of the systems we use in aesthetics/dermatology are Class 4. That means they emit more than 500 milliwatts. With modern diode and Q-switched/picosecond lasers, the power can range from a few thousand watts to millions of watts per… Continue reading Eye Safety – A warning! I did it again…

What are the differences between lasers and IPLs?
I am asked this question often. So, I made a wee video to explain the main differences… I hope this makes things a bit clearer. Mike.
More about laser power – average versus peak!! With videos…
Following my post yesterday re laser power, I thought I’d explain further using the medium of video… The above shows a Q-switched Nd:YAG laser outputting pulses of energy 0.3 Joules in 10 nanoseoncd pulsewidths. These equate to a peak power of 30 million Watts in each pulse (30 MW). However, the ‘peak’ power relates to… Continue reading More about laser power – average versus peak!! With videos…
Laser Power – How important is this?
Average Power vs Peak Power Someone asked me recently “Should I buy a 5000 Watt diode laser or a 3500 Watt laser?” I was a bit puzzled… I‘ve noticed a few laser companies promoting their systems om the basis of the “power”. With quotes like “the most powerful laser on the planet” and similar nonsense,… Continue reading Laser Power – How important is this?
