I was wondering what the most powerful single mode laser diode is. Would be great if we could compile a list of them by wavelength. Surely this will prove useful to many.

So out of boredom, I decided to take apart my no longer used LG GH22NP20 DVD re-writer and to was lucky enough to find an open canned red diode which I then pressed into an Axis module which in turn got inserted into a custom made Aluminium heatsink with a small fan to keep things cool and was...

So I've been out of the laser scene for quite some time now but every now and then I like to dive back in and experience what I've been missing. Got my eyes set on a Sanwu Guardian laser however I'm unsure of two options: The host material and diode. From experience, would the white copper...

Hello, I've recently moved to Italy and was wondering if I could play around with my lasers at night or is it Illegal to do so in Italy? What are the laws for handheld laser pointers? Thanks!

Hello people, So I've decided to fire up my laser after more than a year of dust collecting and I inserted the 18650 battery the way I usually do with lasers and flashlights (negative side towards end cap). I turned on the laser and nothing happened. Then it hit me. I had realized that this...

Hey guys, I want to sell my slightly used RPL laser because I am losing interest in lasers. Included with the laser are both tailcaps, one with a safety key and the other that limits output power, a full laser certification report as well as the case it came in. The laser has been sent back to...

Hey guys, I have a used beam expander that I originally bought from ebay with a c-mount that has been custom made by LPF member Ehgemus especially for my Optotronics RPL laser. The beam expander is in very good condition with some minor scratches to the anodizing. it was as like that when I...

Hello, I was wondering if it is possible to remove light scratches from a glass collimator lens. I was trying to clean one of mine and I started getting a flare light artifact around the laser dot. I've tried alchohol, acetone with q tips and microfiber cloths as well as polishing with dremel...

Being an Omega watch owner myself, I was watching this video on youtube: "http://www.youtube.com/watch?v=NPR-P0r_3fE&feature=youtu.be" and got really excited 48 seconds into the video when I saw a very high powered 532 nm laser etching numbers in the ceramic bezel of the watch. How powerful do...

Hey guys, I want to take advantage of the sale laser glow is having at the moment to get myself a yellow laser. I have 4 options: The Rigel 6 or 10 or the Rigel HV 5 or 10. I am not sure what wavelength I will like more since I havent seen any of the two in person nor do I know how much power...

Hey guys, I want to eventually own every wavelength of laser light available, so I am now looking for either a 473 nm laser or a yellow/orange laser. I would prefer if the beam was bright enough to be seen clearly at night and would prefer a pen style over a portable one for the sake of...

Hello people, What object if any would be able to absorb all of the laser's energy in the form of heat? I was thinking a black body would actually do this, but when I shine a laser beam at a black surface, the dot is much dimmer than if I were to shine the same beam on a white surface. If in...

Hey guys, I've read somewhere on the forums that such a diode already exists. Where is it at in the production process right now? Can one purchase a laser with this diode installed? If yes, then please let me know where I can get myself one. Thanks!

Hey guys, I was looking through my things and found a Mini Maglite with no reflector and no front lens but with a working bulb. This flashlight was bought with the intent of making a direct drive red laser from a CD-RW drive when I had just started my journey into the world of lasers. That...

Hello people, I was just wondering what the reaction of ancient society would have been had we traveled to the past and shone a laser at them. Would each civilization have a different reaction to the action?

Hey guys, I was just thinking about one of newton's laws of motion: "every action has an equal and opposite reaction", and was wondering if that would also apply to a laser. Would an infinitely powerful laser push itself backwards in the opposite direction of its beam or does that not happen...

Hey guys, I've owned a 445 laser for quite some time now, but have never been able to use a LPM to test its output power. However, how would I best estimate its power output knowing the following facts: The flexdrive's current is set to 1.5A, and it pulls around 2.2A from a freshly charged...

Hey guys, I was just wondering if one could replace the use of batteries in any electronics with an AC or DC adaptor or maybe even a switching adaptor. For example: My 445 nm laser pulls around 2.2 A from my 4.2V battery. Could it be okay to connect a power supply of 4.205 V, that can supply a...

Hey guys, I've always wanted a high output/quality greenie that would fit in my pocket wherever I go. Ever since I got my X25 from Nova Lasers, I was hooked to the great customer service and the excellent product they have sent me. If anyone has an endeavor he/she wants to sell, then...

Hey guys, I have a used pair of senns hd800 cans that have been used for no longer than a few hours. I bought them new from a Sennheiser dealer so i have the original box and receipt. There is a minor scratch at the bottom of the left headphone. Also, please note that the original cable...
