These were all done with my new 35mm f/1.8, it's better quality than the other lens and a perfect focal length for a lot of what I do. 445 just spoils most of the pics with a blue wash and my Rigel doesn't lase yellow at all anymore unless it's really warm.

Great! Wish I could do that!

I presume the mirrors are front surface mirrors. Are you using any fog?

When you say "purple" is that 405nm? What power are the lasers? [sorry for all the questions!]

405 is purple - it's just a newwish pen so power I have no idea, but the beam is visible in the dark. I used incense just to purify the beams a bit. Without it they appear more "gritty" - I'm sure you've experienced the same. the green is a 100mW portable, the red is a 30mW portable, the yellow is a highly temperamental ~10mW portable, the 473 blue is a lab ~150mW, bought it recently for £100, unbelievable price for a high quality DPSS that can be left on for hours at a time.

they are just mirrors for doing makeup or shaving etc, few quid off the 'net.

Just need a decent yellow now!

Was the 473 blue second hand or would I also be able to buy one for £100 :) [With labby do you do a special power supply too?]

Normal mirrors - wow - I just assumed you would have got a shadow beam showing where it reflected off the glass.

Yellow - sooo expensive :(

I bought the 473 from one of our fellow members:
http://laserpointerforums.com/f39/fs-150mw-473nm-dpss-head-driver-psu-150usd-p-p-91105.html

I don't think you'd often find a 473 for £100, even a lab. Lab 473s do seem to be surprisingly cheap sometimes but I've only ever really seen the cheaper ones in the tens of milliwatts range. That's why I bit twirly's hand off when I saw that thread. It's missing the cover from the driver and is an older model so it needs a separate 5VDC power supply for modulation (which I fashioned from an old ATX PC power supply by crossing some wires - literally). It's still across the room from me now shining away since I started using at the beginning of the night two hours ago, stable as a rock. The normal power supply and laser head are just different components but they're part of the package that you'd call a lab laser really.

Yellows are ridiculously expensive, yes. Which is why I'm having a very hard time about buying a more powerful one as I find it hard to part with that kind of money.

Not sure what you mean on the mirrors - they reflect a laser beam in the same way it reflects all other forms of light - back at an angle that it hit the mirror.

Just seen your photos again - I still can't believe how well your 405nm has photographed. I have so much trouble with my cameras. Maybe it's the due to my 405nm being a cheap ebay pen.

My 405 is just a "cheap" ebay/newwish pen, like a few of my others but they're all soldiers - I've ran them for over an hour constantly before without problems. The 405 I think is quite powerful as the beam is visible even in a lit room if you get the angle right.
