Hello All,
First let me confess a dreadful secret: I'm a long term cross-dresser but
also a competent and experienced electronics design engineer. Unbelievable
but true! Over the years I've spent several thousand pounds on laser hair
removal (ugh I hear you say whereas I usually say ouch).
For those who don't know about this, the laser light resonates with the
melanin molecules in dark hair to produce local heating which kills the
root. Other tissue is ignored. Sadly it only works when the hair follicle
is in a growing phase which most are not at any given time. The net effect
is that many treatments are necessary and there are always some left.
The laser companies cope with this by 'spotting'. That is instead of
charging to scan a whole area (for those interested it's a bee sting every
250mS as the head is moved) they go after individual hairs or clusters at 1
UK pound a shot, with an active head of about 9mm square! Count the hairs
on the back of your hand and see what that adds up to!
Now to the crux of my post: The light nowadays comes from semiconductor
lasers. I am a power supply designer and can produce controlled power
pulses at whatever level may be necessary to drive an appropriate laser
diode to produce an appropriate pulse. Because I'm after individual hairs,
not much more than a point source is necessary. I know what flux, duration
and wavelength is needed but I don't know anything about high power laser
diodes. Is there anyone who has any special knowledge? Is anything
possible for say a couple of hundred dollars?
Should anyone be reluctant to comment for safety reasons, be aware that I
value my own skin more than most and I'm technically competent.
I look forward to any replies.
Regards,
Pauline Aston.
PS. So many engineers are cross-dressers, MIT has it's own support club for
them!
