Current state of small laser technology

AI Thread Summary
Current advancements in small laser technology are being explored for creating lasers that emit non-visible light and fit within a 0.5cm dimension. The feasibility of integrating a power supply, such as a CR927 or SR41 battery, into such a compact design is a key consideration. Discussions highlight the challenges of energy capacity within such limited space and whether it can support detection at distances of 6ft or greater. Participants are encouraged to share insights or direct inquiries to relevant sections of the forum for further exploration. The conversation emphasizes the intersection of size, power, and functionality in developing these small laser systems.

I am interested if current laser technology exists such that a small laser can be made that emits non-visible light, is .5cm or less (at it's largest dimension), and can detect at distances of 6ft or greater. Please feel free to direct me to other areas of the forum to direct this question if more applicable.

Including the power supply? What kind of battery energy fits in 0.5cm^3? Is that sufficient for you?
 
CR927? SR41?

Edit: Geez, you can't post just the name correctly as it is considered to be capitalized and changed to Cr927...
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'How can I find the cleanout for my building drain?'

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...
