Dear all !
thank you very much for the answers, really this forum is just terrific !
Yes, the coherent laser seems the most addapt to my need ...
i'll take some more time to think
therms of 1% is a long shot for the chinees lasers i think
thank you again
Thanks a thousand Diachi !
I can see clear ...
I want to use one of these lasers (mays be the more expensive one) for a Raman Spectroscopy set up (i'll use a power of 100mW maximum).
What are you recommendations?
I have a question about the caractersitics of lasers vs the nature of the laser.
I have the choice between two green lasers 532nm, one is DPSS the other is Solide state.
Please, can you help me to decide whch one si the best.
especially about the laser stability, lifespan, laser...
Thank you Encap for the wire !
Yes, indeed, they have very good products, even if they are chineese .. and i can't get the prices
for the filters ... i need really a narrow one 0.1nm ! and this is really expensive (~300$ !)
Also, i got an offer from thunderoptics.fr ... i think a very good...
I am looking for a hight quality 532nm Laser with real power of 50mW.
I need a bandwidth of less than 0.5nm
all the lasers i got on ebay or any where else are deceiving, as the line is really broad and the power @ 532 is really low (when i filter only the line @ 532nm)
i was shocked...
Dear Diachi !
Thanks a lot!
Yes, the spectral bandwidth. In fact, i have contacted them, and they answered that they did measur eit, and it is lower than 30MHz at 60mW! what it means that it is much lower than 0.01nm ! what is really very nice!
I am using these laser diodes for Raman...
Dear all !
I tried several diode lasers from ebay ... but i al almost upset ...
the laser bandwidth is to large.
I read about the DJ532-40 greeb laser diod of 40mW from Thorlabs.
It seems that it has really 40mW and this power is really at 532nm
is there some one who has tried it before?
I have a LPC-836 laser diode, but i can't get it's datasheet, please:
- Is there any one who can help me getting this datasheet?
- what is the best current to use it in a continus mode (20mn or even 1 hr in continous).
will i need a heatsink?
all the best
