My name is Walter Luhs. I am the owner and creator of all laser kits on https://luhs.de. I am holding a degree as engineer, physicist and PHD in physics (Photonics) since 1983.

At all locations inside your ruby rod where the pump intensity is not above the threshold, self absorption of the 694 nm will occur. You may calculate the Rayleigh range for a 100 mm lens, this gives you an idea how long the well pumped length will be. I fear, the rod is by far too long. Ideal...

A longer focal length will reduce the pump intensity, you might not reach the threshold.

CW Ruby laser pumped with a 405 nm laser diode: Please have a look to: https://luhs.de/ and https://www.osapublishing.org/osac/abstract.cfm?uri=osac-2-1-184 I hope you will like it.
