I'm looking for a fairly detailed answer. I haven't really found anything useful on google except for ads selling them (for very high prices).
I know that 532nm green DPSS lasers basically have an 808nm IR diode that pumps a solid state Nd:YAG crystal to produce 1.064um IR lasing, which is then frequency doubled in a second harmonic crystal and hence produces 532nm green light. That's the sort of detail I'm looking for (preferably with types of crystal) for 473nm blue lasing action! Thanks!

What is the molar solubility in water of Ag2CrO4? (The Ksp for Ag2CrO4 is 8 x 10^-12)
-------------------------
What is the final concentration of barium ions, [Ba{2+}] in a solution when 100 mL of .10M BaCl2 is mixed with 100 mL of 0.050 M H2SO4?
---------------------------
When 100mL of 1.0M Na3PO4 is mixed with 100 mL of 1.0M AgNO3, a yellow precipitate forms and [Ag+] becomes negligibly small. Rank the ions renmaining in solution in order of increasing concentration. [Na{+}] [NO3{-}] [PO4{3-}]
------------------------
Could you be thorough with the explaination?

My company has an insurance claim against damage caused by lightning. The insurers are claiming that the building is not earthed properly. But our building is properly earthed as we had an electrician come in and re-earthed the building a few months ago but the spike managed to pass thru both the electrical and telephone wires and damaged equipment such as: phones, TV sets that were turned off, Network Hub and CPU & Monitors that were using UPS, etc. Note the UPS are still working to date
