SUMMARY

The discussion revolves around the challenges of creating custom connectors for a rack mount quad lab laser, specifically using two SMA905 connectorized diodes to pump a Spectra Physics Millenia 1st generation 1064nm laser cavity. The user seeks to cleave 5-meter fibers from a Coherent Laser Verdi to create a hybridized delivery fiber with FC male connectors, maintaining an 800um core and a numerical aperture (NA) of .22. Difficulties arise from the fiber industry's reluctance to work with existing fibers and the inadequacy of available connectors, particularly regarding thermal performance and throughput for 40-watt CW 808nm applications.

PREREQUISITES
  • Understanding of fiber optics, specifically SMA905 and FC connector types
  • Knowledge of laser pumping systems and their specifications
  • Familiarity with thermal characteristics of materials used in fiber connectors
  • Experience in cleaving and assembling optical fibers
NEXT STEPS
  • Research suitable FC connectors from Molex or Polymicro for high-power applications
  • Explore alternative methods for cleaving and assembling optical fibers
  • Investigate thermal management solutions for high-power fiber optic systems
  • Learn about custom fiber optic cable manufacturing processes and suppliers
USEFUL FOR

Laser physicists, optical engineers, and technicians involved in fiber optic systems, particularly those working with high-power laser applications and custom connector solutions.

I have a rack mount quad lab laser it has 4 series wired SMA905 connectorized diodes.I am wanting to use two of the to pump a Spectra Physic Millenia 1st generation 1064nm laser cavity which has 2 FC female connectorized collimation lenses. They pump a 4x4x7mm water cooled YVO4 crystal from two sides.

I have 2, 5 meter long fibers that were originally part of a Coherent Laser Verdi. I want to cleave the ends of these and create a hybridized delivery fiber that preserves the original pump diode specification of an fc male connector , 800um core a NA of .22.

I am having great difficulty with the fiber industry they either will not use my fibers or will not outsource the FC connectors many are just trying to drill communication connectors to oversize with no consideration of issues with throughput of 40 watt CW 808nm, and heating from losses in the epoxy binder and coupling losses.

Most of these connectors are stainless steel and have very poor thermal characteristics.

The few companies that do make suitable connectors in particular molex division polymicro do not seem to want to sell product not incorporated into a finished jumper??

A real pain in tha Ah posterior!

Any of you physicist's with any ideas for me short of winning lottery or putting my project on hold for 12 wks lead time to have cables built, to pump a 20mm type 2 SHG would be greatly and humbly appreciated, i am technically inclined to a sufficient degree to be able to build my own cables with surplus items if i can just find the right connectors.

Hmm, sorry @anorlunda. I'm not familiar with those fiber connectors. Hopefully by now other connector systems are standard.
