Dear all,

being hit by a sudden severe decrease of laser output on our Zeiss solid
laser 638nm, 75mW I am wondering what the average life time of such
lasers is, as I can't find any documentation on that. I dont feel
comfortable with the information by the manufacturer. Aslo I would be
interested in your experience of repair prices for a three year old
spinning disc laser replacement. You may also contact my by PN on mail
to discuss.

Best

Ralph

Hey Ralph,
   I've been working a bit with these laser diode, including pushing them
to their limits, so I feel reasonably good discussing their failure modes.
One of the first things to always double check is the fiber alignment, as
small misalignments can lead to significant power drops due to poor
coupling inefficiencies with any laser.  Negating that, the biggest problem
I've run into with the red laser diodes is keeping them cool.  I'm not sure
of the materials science behind it, but compared to blue diode lasers, they
seem much more prone to failure due to overheating.  If you look at the
spec sheets for these diodes, you will also see a pretty steep de-rating
with temperature and a low max operating temperature.  As a result, the
vast majority of these diodes are themoelectrically cooled (TEC) to squeeze
out higher powers without appreciably cutting into their life-span.

   As an example, this is one of the better 638 nm laser diodes out there,
and you will see that the max operating temperature is just 40C:
http://www.ushio-optosemi.com/documents/uos/products/UOSE_DS_HL63193MG_R0.pdf

   When they do over-heat, I've found their output will suddenly drop a
couple orders of magnitude, and if it was a TM00 beam to start with, you
will get some higher order transverse modes instead.  If you look at the
die itself, it will be noticeably warped, so it then becomes clear why the
lasing efficiency and beam quality dropped so much.  We've pushed three
diodes past their limits, and all have failed this way, where rather than
just going out, they just get dimmer with higher order transverse modes.
If you continue to use them after this failure, you will see that they
gradually get progressively dimmer in a log-like manner.

   Therefore, if it isn't a fiber coupling problem, I would wager that the
diode over-heated (or much more unlikely - a spec of dust got onto the face
of the die), and kicked the bucket.  All commercial laser modules I know of
will come with a spec sheet that lists the expected lifetime of the laser.
Generally, I've seen 2,000 - 10,000 hours listed, with 3,000 and 5,000
hours being the most common ones I've run into.  I would look up the
manufacturer label on the laser, and that should give you the spec sheet.

Cheers,
   Ben Smith

Dear list users,

THANK YOU! I recieved a large number of very helpful personel messages
on this topic. Quite a few things were new to me and certainly will help
to discuss with my vendor on serious grounds about a solid state laser
hardly ever used at more than 50 % output just dying away after only
just 4.000 usage hours in a temperature controlled lab space.

I appreciate all of your valuable time spent on this issue!

Ralf
