An exotic pictures collection request.

I'm not sure with the multi-line green wavelengths... wouldn't it be 532nm, 537nm and 543nm? Nd:YVO4 makes IR lines at 1064nm, 1074nm and 1086nm that can be doubled, unless it acts like SFG rather than normal DPSS? Still even in that case the rounding wouldn't make much sense as normal SFG would round DOWN from 537.4nm to 537nm... I'm just a critic when it comes to numbers

Wow Cheech! 612 is a really great orange... among my all time fav's from all I've seen. I think it has it all over 589 & 593nm except I also do like higher output! :eg: GH

I'm not sure with the multi-line green wavelengths...

I'm just going by the spectrometer readout.

 

[cheech226]

the graph don't lie cyparagon!

i'm sure about 100mw or so of 612 would be great. but for me 100mw of 589 or 594 would be better. and a watt of 660 even more so...

 

[ZRaffleticket]

Huh... well, considering those are in increments of 2 I'm very close to right! 532nm looks like it's directly on the bar... as for 537nm it looks like it's maybe .2-.3 off, and about .1nm off for 543nm... do you have ways to pinpoint what their peak WL's are from that graph (other than eyeing it up)?

 

[Cyparagon]

Yes, but it is like looking at a ruler and reporting a reading in microns. The software has precision up to 0.001nm or so, but the hardware doesn't have the same precision. Your eyeballing is about on par with hardware capability.

 

[ZRaffleticket]

Aye, gotcha. Just trying to check if my exotic DPSS sheet is accurate

How powerful is your 473nm digital?

How powerful is your 473nm digital?

I'd assume like everyone of the other B&Ws with the red/black wires cut. 15-20mw maybe?

 

[TheTeslaWarrior]

sorry for the crappy pictures

HeNes with their similarly colored diode/dpss counterparts (the red HeNe had to sit out due to catastrophic PSU wire malfunction)

589nm and 473nm

488nm

594nm and 488nm

ML argon, 543.5nm, 594nm, 650nm

lastly 9 lines of ML argon

 

[ZRaffleticket]

ohh... It saddens me that this thread showcases two lasers I want, 589nm (functioning to my specs at least) and a multi-line argon

@digital Alright, just curious if you had a higher power one or not

 

[mountainmike7420]

great pics guys! wow

 

[ZRaffleticket]

I took a few pictures with my labby a few days ago with the intenton of putting them here.
Setup: labby sitting on a piano stool, pointed onto a mirror (I tested in low power), reflecting back next to my door.

The rest should speak for themselves unless I have a comment...

How do you guys set those diffraction sheets up in front of labbies? I guess either tape or distances work as the air cooling always gets in the way haha

 

[LtKernelPanic]

I've used my helping hands to hold diffraction gratings, lumia glass, etc. in front of my ML argon many times. Works nicely. I'd love to take my argon outside on a dark clear night and have some fun with it. Too bad the damned PSU weighs in at almost 50 pounds (22.7kg) alone. I still may haul it out sometime.

 

[ZRaffleticket]

Heh, that there is why I don't play with my argon much. Too much effort to haul these around, and mine's not even ML so it's not really worth it.
