Documentation/Manuals required for Quantel Brilliant/Brilliant B

[plazmatron]

Hi

does anyone on here happen to have manuals for the Quantel Brilliant/Brilliant B Lasers please?
These were produced in the mid 90's and the only info I can find is from brochures.
I am specifically interested in any documentation relating to the Doubler, Tripler and Quadrupler modules.

Cheers!

Be very , very, patient with the quadrupled laser.
The thermal time lag in the crystal , depending on its cut , can be very significant. Again, depending on the crystal material, be patient with the adsorption effects. Adjustment time constants of 20 minutes were not uncommon, on the units I worked on.

I've had more then one impatient user tear their hair out over the deep UV phase matching. Plot the dips vs adjustment screw position. Typically a gorgeous peak shows up, stays for a minute or two and then falls to 30% of power. Generally there will be one stable position out of many.Can be an hourly or daily process. Often totally lost on power down


The thermally driven refractive index
changes can be a bear. Especially if the crystal is not heated or the temperature setting is off..
Patience when tuning. A Joule meter is generally required.

Third harmonic is not so bad.

I do not have any manuals for you. Sorry

Depending on dopant and growth process differences, it is not unusual for software models to vary up to +/- 2 degrees angle from batch to batch and factory to factory. KTP with Cesium to stop Grey Tracking at high powers is very different from pure KTP for the cut angle, as one example.

Pro tip, professional systems often power down the diode, lamp, and cooling, but leave the crystal heaters on. There are several reasons for that, not the least is humidity damage.

Low rep rate systems usually breed a few master users, the rest will seek counseling or let the master user warm things up. Seen that at many grad schools.

BTW, cleaning compounds for many types of UV, OpO, OpA, crystals should have a strong smell of bananas, ie Acetates.

The other fun involves index matching fluids when you can't coat by thermal means. Shudder, seals and o-rings in solvents. Sol Gels have their purpose.

Ethyl Acetate Stinks, Butyl Acetate even more so. Say no to residual H2O

Try Richard Anderson at Anderson Lasers for the manuals.

Thanks for the tips! So much for the claimed plug and play in the sales blurb!

I only got the Doublers, Tripler and Quadrupler, the Laser was not part of the auction, but I have had a YAG project on the go for some time, so it will be interesting to try out!

Cheers!
