Documenting backlog. Especially around Pockells cell / EOM repair
 +
 
 +
Open question about q-switch polarity. Tried putting my (mostly bad) EOM in my laser forwards/backwards and positive/negative polarity. Only forward positive configuration fires. Not sure if polarity reversal is bad
 +
 
 +
Scrapped ezlaze Kevin had in dire shape to get sacrificial q-switch. Housing very different, but core looked the same. Unfortunately, does not seem to work in my original laser. Also tried reversing it, but didn't help. NOTE: Kevin has a second identical loose EOM assembly. We should try it
 +
 
 +
Played briefly with transferring fluid from sacrificial larger EOM. Had issue with bubble, also still unclear if fluid matched correctly
 +
 
 +
 
 +
Pockels cell research:
 +
 
 +
*Probably made by Qioptiq, but may be branded Gsanger or LINOS
 +
 
 +
<blockquote></blockquote><blockquote>Due to a series of acquisitions, Qioptiq</blockquote><blockquote>has an impressive history and pedigree, benefi ting</blockquote><blockquote>from the knowledge and experience of LINOS,</blockquote><blockquote>Point Source, Rodenstock Precision Optics, Spindler</blockquote><blockquote>& Hoyer, Gsänger, Optem, Pilkington, Avimo and</blockquote><blockquote>others.</blockquote>
 +
 
 +
 
 +
Did a lot of research on the fluid. Index matching fluid (IMF) is required due to the high efficiencies required to make a cavity resonate.
 +
 
 +
https://microwiki.org/media/qti/qti_an_dry_pockels_cell_vs_wet_pockels_cells.pdf
 +
 
 +
*Great paper on IMF choices
 +
*TLDR: FC-43 for most applications, but more exotic choices if you don't care about carcinogens and/or cost
 +
 
 +
 
 +
Ordering:
 +
 
 +
*quantumtech.com: "We have index matching fluid $175 for 30ml bottle and available from stock.  We charge for repair would be approximately $400. "
 +
*Tried to order FC-43 from Sigma, but they denied my order

Visit Kevin, got:

  • 2x ezlaze laser head
  • 1x ESI power meter head
  • 1x power meter head w/ controller


Tests on my ezlaze:

  • DB25 only: motors twitch at startup. Interlock lit red, cannot turn on
  • Both connectors: motors twitch at startup. Interlock lit red. However, press "ON" moves from red interlock to yellow emission
  • When hitting "ON", a loud relay is heard in the controller

Kevin-1 (K1):

  • Missing tilt plate
  • Missing tilt plate screws
  • No camera adapter
  • Motors do not twitch at power up
  • Unable to bring out of interlock
  • Missing shutter
  • LCSII....ah not exactly the same

Kevin-2 (K2)

  • Motors twitch at startup
  • Bent power connector. Was able to bend back into shape
  • Mounting plate screws but no mounting plate
  • Has shutter
  • EZLAZE 532/355
  • Beam profile uneven (as seen through laser glasses). TODO: point at camera?
  • Sensor 3" from laser, 10 sec average
    • 500L: 65 uJ
    • 1000L: 124 uJ
    • 500H: 192 uJ

Documenting backlog. Especially around Pockells cell / EOM repair

Open question about q-switch polarity. Tried putting my (mostly bad) EOM in my laser forwards/backwards and positive/negative polarity. Only forward positive configuration fires. Not sure if polarity reversal is bad

Scrapped ezlaze Kevin had in dire shape to get sacrificial q-switch. Housing very different, but core looked the same. Unfortunately, does not seem to work in my original laser. Also tried reversing it, but didn't help. NOTE: Kevin has a second identical loose EOM assembly. We should try it

Played briefly with transferring fluid from sacrificial larger EOM. Had issue with bubble, also still unclear if fluid matched correctly


Pockels cell research:

  • Probably made by Qioptiq, but may be branded Gsanger or LINOS

Due to a series of acquisitions, Qioptiq

has an impressive history and pedigree, benefi ting

from the knowledge and experience of LINOS,

Point Source, Rodenstock Precision Optics, Spindler

& Hoyer, Gsänger, Optem, Pilkington, Avimo and

others.


Did a lot of research on the fluid. Index matching fluid (IMF) is required due to the high efficiencies required to make a cavity resonate.

https://microwiki.org/media/qti/qti_an_dry_pockels_cell_vs_wet_pockels_cells.pdf

  • Great paper on IMF choices
  • TLDR: FC-43 for most applications, but more exotic choices if you don't care about carcinogens and/or cost


Ordering:

  • quantumtech.com: "We have index matching fluid $175 for 30ml bottle and available from stock. We charge for repair would be approximately $400. "
  • Tried to order FC-43 from Sigma, but they denied my order
    • https://www.sigmaaldrich.com/catalog/product/sial/77299
    • Heptacosafluorotributylamine (Fluorinert™ FC-43)
    • 5 mL: 52.60
    • 25 mL: 235.00

QuikLaze

I asked for a ezlaze manual and was given a quicklaze manual...w/e. Looks like they share a lot of common components

Interesting excerpt from manual: The QuikLaze is designed to operate on specially modified Mitutoyo FS60Y and FS50 and Ready products A-Zoom and S-Scope microscopes. Become familiar with your microscope before attempting to install the QuikLaze.

The quicklaze power supply looks pretty similar to the ezlaze power supply...possibly compatibile
