The lamp must be submerged in flowing, non-conducting DI water. You need to email NEOS and see if "Giant Pulse Suppression" is enabled / integrated on the Q-switch driver.

I'm not so sure that is a flashlamp. I think I'm looking at a CW krypton arc lamp.

As that appears to have an integrated "BUCK" mode switching lamp driver, you have a long way to go as lamps are finicky and easily can explode. You have to figure out how to start the lamp, shut off the start boost voltage, and regulate the lamp current. Some where in there will be a series injection ignition transformer with greater then 160 VDC at 20-30 amps coming out of the secondary. When it fires, it will typically produce 20-40 KV riding on top of the DC coming from the buck switcher. The lamp is a current controlled device, while it has a slightly positive delta on its voltage/current curve, it is a device that must be current limited or it will run away. At the same time you have to have flow and water quality/tank level monitored.
!
To give you an idea, we usually let water flow thru the de-ionizer cartridge for four to eight hours before starting the lamp. Any serious conductivity in the water and the power supply, lamp, and rod usually die in a few hundred microseconds. Little details like that matter.
!
Diode pumping is out of the parameters for that rod size and doping.
!
Your calling it a 110 Watt, I see something more like sixty based on the lamp size...
!
If it all possible, using the existing controller is a must. Are you sure there is a not a big box with a separate lamp supply in it?

Q-Switched 1064 and 532 nanometer laser light is, IMHO, one of the most dangerous things on the planet, especially for a beginner. You need certified and tested safety goggles at these power levels and a safe beam stop. If you have never worked with sixty to two hundred watts of laser light, you HAVE NO IDEA what a safe stop is, and how dangerous the scattered light is. THIS IS NOT A TOY. Telling me not to give you the safety advice, that you heard it all on LPF, is about the quickest thing you can do to make me NOT want to help you. Less then 0.15% of the LPF population has ever been anywhere close to something like this. There are probably less then 10 people participating on LPF that could tell you how to work on one of these.

Looking at the device cooling, it appears to be a low duty cycle laser, I'm not seeing a large cooling system there.

Are you sure there is not a separate lamp psu box inside the unit that I am not seeing in your pictures?
