It’s the kind of thing us physicists do!! It keeps us off the streets at night…… So, to calculate this number we need to… Continue reading How many photons are in a laser pulse?
Have you ever wondered how bright your laser is? Given that it outputs millions of watts of light (in both 1064 and 532nm) you might imagine that it is quite bright…. Well I took a couple of videos to see for myself. Our laser safety glasses are rated at OD7 – that means if 10… Continue reading How bright is your Q-switched Nd:YAG laser?
Just thought I’d post some photos which I took earlier to view the brightness of the 532nm wavelength compared with the 1064nm line on a tattoo… Note: all photos and videos were taken using an iPhone 6. The top photo shows the tattoo just before the laser is fired at 1064 nm. The… Continue reading 532nm treatment of a tattoo – what does it actually look like?
Just to let you all know, I’m also an LPA and a committee member of the Association of Laser Safety Professionals (UK). This means I can come to your place and check your laser safety situation, recommend any changes or additions you may need and advise on the legal and Health & Safety side of… Continue reading Laser Protection Adviser (LPA)
