Dear listserv,

has anyone put these wickedlasers (or equivalent price/power) on
confocal, MSIM, single molecule localization etc scope (and figured out
how to control on/off, intensity, from USB or other port)?

http://www.wickedlasers.com/krypton?utm_source=Wicked+Lasers+New&utm_campaign=bd89072d39-S3_August_20128_17_2012&utm_medium=email
532 nm,   750 mW, $999.95, Spyder Krypton
445 nm, 1250 mW, $399.95, Spyder Arctic

If you have, web page or other instructions, on how would be great.

George
p.s. if someone can explain to me (without cheating by asking the
company) the choice of glasses in the home page video,
http://www.wickedlasers.com/index.php , that would be great. If you make
it through the first video, click on the Arctic Popcorn video link. And
of course, "do not look at laser with remaining eye".

Why would I want to buy two lasers to pop one kernel of popcorn when four cell phones (which we already have) can get the job done with their microwave antennae?

Secondly, these things are really dangerous.  But if the laser company has the same liability as gun companies (as in none), buy stock because this is a sure winner.  If they work as advertised, lots of destructive teens and adults (mostly men I bet) will be ordering these and certainly our lab too.

I can't find any details about the actual design of the laser modules the website, but I looked into getting a very similar 1W blue laser pointer that was on offer at deal-extreme. It turned out that the module was originally designed for laser projection/lighting applications and was a number of separate lower wattage modules fabricated side by side on the same die (like some high power LEDs). This type of laser is unsuitable/less suitable for microscopy applications due to the extended  source area and corresponding inability to be focussed down to a small spot.  



To switch / control intensity your best bet would probably be an external shutter and/or filter wheel. We use viasho lasers which are positioned, both in price/W and capabilities/quality, somewhere between these and classical 'scientific' grade lasers. The viasho modules have either TTL or analog control via bnc, but switching the lasers using these inputs results in instability and mode hopping as they warm up and cool down (I suspect the inputs are designed for more rapid modulation on timescales less than the thermal relaxation of the laser die), making shutters and a filter wheel the most practical method of control.

As to the glasses, they sell them separately as OD2 glasses without specifying which of their lasers they should be used with, so I suspect they've just specced them to be OD2 or better at all wavelengths of laser they sell. This actually seems like a fairly responsible/ pragmatic approach for people selling a product like this.

cheers,
David

One thing the Wicked Laser specs do tell you is that the beam is very elliptical (2mm x 5mm for the blue one) which would also be a hassle for confocal use.  The green one (why do they call it Krypton?) seems better.  

There is a story going the rounds of a man who bought one of these (with laser sabre).  He put his safety glasses on and turned it on but naturally couldn't see it.  So he took the glasses off and shone it in one eye - still couldn't see it.  Then he tried the other eye - and never saw anything again.  

Sale of these lasers to private customers is certainly illegal in Australia.

Dear George (Sorry for the double whammy! I meant to reply to all...),

I have been in contact with Wicked lasers about controlling their laser
via Arduino, with limited success. They say they will look into it, but I
somehow doubt that they take me seriously... I would like to use it for
Light Sheet Microscopy made with a cylindrical lens, so it wouldn't be as
critical in terms of beam quality as it would be for Laser Scanning
Confocal Microscopy.

Maybe if we all made a concerted effort to express our interests in using
their "inexpensive" lasers in our Mad Science labs, they would take a
hint... ;-)

You could almost pump a Mira 900 with their 532 nm laser*!!

Regards,
Pete

*That being the only real use for such a laser line, and for sexy laser
pointers that is...

Hi Pete,

May be simpler to use lasers currently sold for laser light shows ...
plus, if you could divert the beam(s) into a nearby conference room (or
disable your microscope safety interlocks in your lab), could put on a
light show for VIP's. See for example

http://www.lasernrg.com/diode-and-dpss-laser-modules.html

George
Of course if you show videos, you'll also be able to cook the popcorn on
stage.

Kryptonite (from the planet Krypton) is green.  Don't know whether it may be used for a laser crystal, however.  Maybe it would be a better weapon against Superman.

Sure, but that doesn't alter the fact that the Wicked Laser Krypton is DPSS (frequency doubled NdYAG) not a krypton laser!

Dear List,

Please pardon my intrusion...

As I watch from the sidelines, this topic seems to have veered from one side
of the spectrum to the other (pun intended). I doubt this following
information is anything new to this prestigious list, but here are the Ion
wavelengths used during the times of initial development, of the many types
of instruments used in this industry and the many others:
 

Argon Wavelength (nm) I-304 I-305 I-306 I-307 I-308 I-310

(If anyone requires individual ION UV wavelengths, I can respond off list.)

As the optical & detector side played catch up with the OEM's desires for a
smaller foot print, so goes the balancing act with producing new smaller
solid state laser systems. This ballet ensues among all industries
worldwide, as new technologies within any given marketplace force those
other complimentary to it; to adapt.  
 
In our opinion, the solid state lasers that we have found to be the most
reliable & prove to be "cost effective" replacement to either water-cooled
or air-cooled ION laser systems on bio-instrumentation tools, are produced
by Coherent, Inc.:

Has anyone investigated the stability of these lasers?  Sure they are

troublesome when you try to image with it...
You might want some RMS noise speciifications before you buy.
