50mW Modules for sale.
On: Fri, Feb 08, 02 05:58:53 PM
|I've got a couple of 50mW 660nM laser modules for sale. One
has a heatsink, the other does not. Both have less than 1
hour of time on them. I'd like $190 for the one with the
heatsink, and $180 for the one without it. Post here if
interested and I'll email you.
Tom B. - Sun, Feb 10, 02 03:21:59 AM Please supply more detail, such as laser module
manufacturer and part number, or at least the
laser diode mfr. and part no. Or some evidence that
this is not a multimode diode that is unsuitable
for holography, as is often the case in this
power range. 188.8.131.52
JDM - Sun, Feb 10, 02 08:45:18 AM Sure: It's a panasonic LNCQ05PS diode, which is 50mW single
mode. It iw being run on an APC power supply that is fully
adjustable for laser diode current as well as photodiode
feedback current. It is housed in a 10mm housing and the
diode is mated to its housing with indium foil and indium
solder (very low temp) for maximum heat transfer. Runs on
3.5-6volts DC, well filtered. If you need anymore info just
let me know.
Tom B. - Tue, Feb 12, 02 01:40:16 AM Sorry if I seemed a bit curt - has anyone reported
success in making holograms with this diode?
JDM - Tue, Feb 12, 02 06:40:08 AM I'm fairly certain that this is the same diode used in the
Samuri II laser system. I don't think there is another 50mW
660nM diode made.
Dooley - Tue, Feb 12, 02 10:28:50 AM I have succesfully made holograms with this diode in
combination with the D&S driver. 184.108.40.206
Thilo K. - Wed, Feb 13, 02 06:56:40 AM A 50mW Laser seems to be very bright. Assuming the use of a
4x5 film, could one use the diode as a pulsed laser system ? 220.127.116.11
Kris Meerlo - Wed, Feb 13, 02 09:12:16 AM Look at my site, I use a 50mWatt laserdiode
with very good results.
Thilo K. - Wed, Feb 13, 02 09:55:47 AM To Kris Meerlo: please convert all big photos on your hp into
small thumbnails, which link to the big ones. 18.104.22.168
- Wed, Feb 13, 02 02:04:21 PM Kris is this 50mW diode that you use for the holograms on
your site the panisonic diode or some other company's diode? 22.214.171.124
Colin - Wed, Feb 13, 02 11:04:17 PM Thilo, Think watts for pulsed systems. 126.96.36.199
Thilo K. - Fri, Feb 15, 02 04:43:58 AM Colin, I´m using a metaphor. Of course, a diode will never be
a pulsed laser; but exposing a quite small film to very
bright laser light acts as if you´re exposing a bigger film
to a pulsed laser. 188.8.131.52
Kris - Fri, Feb 15, 02 05:02:37 AM Hello Thilo,
I don't know what kind of diode I have ( Brand )
It is a module including ( of course ), driver and
optics.HB komponente in Germany ( HB 650/50 )
I made superb holograms with it, very deep and bright.
Yes I know, to download my homepage takes time, in the
near future I make a new one with thumbnails 184.108.40.206
Colin - Fri, Feb 15, 02 12:23:51 PM It is also important to know how short of a pulse you need.
If the object is moving very slowly you can use a longer
pulse. If it is a turbine blade in a jet engine the pulse
must be shorter. If you look at slavich.com there is enough
information to calculate how much energy is needed. For
very short pulses it is common to latensify the film. I
will be glad when the pulses I need are short enough to
make a electronic timer. Right now I use a black card. 220.127.116.11
