Some time ago I visited my fellow glassblower and he made this laser tube for me from fused quartz. It has two side arms for placing copper halide in them an electrodes taken from linear flashlamps. I placed then the copper chloride that had unknown purity and quality. It had already changed...

So, I have been away making a new fully homebuilt laser. It is a manganese metal vapour laser. The laser tube is fully homebuilt. It is a self-heated tube. The main part of it is a ceramic bore tube with 14mm inner diameter and 60cm long. This tube is sorrounded with a layer of ceramic wool...

Here I'm starting a thread about the most high-energy laser that had ever been manufactured commercially for general lab use. The GOS-1001 Nd:Glass laser, that is rated for 1000 J of output energy! And it is the true peak of my collection. A few days ago I managed to get first coherent photons...

Does anybody have any experience in the art of glassblowing? I have a fellow glassblower, who can make neon sign tubes and custom gas discharge lamps for spectroscopic research. Also he refurbished several gas lasers for me. I cannot ask him forever to do something for me, so I asked to...

I've got a couple of relatively high power Nd:YAG lasers, so I had a regular wish to frequency double one of them. My expectations were like: "OK, I'll take a 125W pumping chamber, insert it between two HR mirrors, place a frequency doubling crystal between the chamber and one of the mirrors...

Hello! I would like to offer this K301V YAG pumping chamber for sale. It has a 6.3*100 mm YAG rod and a DNP-6/90 CW crypton arc lamp, with the dimensions of the arc part 6*90 mm correspondantly. Maximum power output can be 125W on 1064 nm or 30W on 1.32 um, the lamp draws about 4-4.5 kW max...

Long time ago I have found a quite big (8*120 mm) ruby crystal from a pulsed holography setup and a couple of big 5 kJ flashlamps. So, I immediately decided to try to build a ruby laser. At the first attempt I tried to put the lamp and the ruby crystal into a cylindrical glass reflector. I...

Before I had made my "homebuilt CVL system" I had a chance to play with the commercial russian CVL called LGI-101. I had found it in the University laser lab NOS in unpacked factory crates. The lab didn't use it for anything since buying it in 1989. It is a first-generation CVL with only 3W of...

Here I will share photos of the lasers I currently have in my collection. Approximately it contains about 60 laser heads, laser tubes, laser pumping chambers and about 15 laser related equipment like associated to laser heads power supplies, cooling machines, dye circulators etc. Less than a...

Here I'd like to share my experience of building a real orange laser! this is a pulsed laser, that uses pure neon as a lasing medium. As far as we know, pure neon can lase only at one IR line in CW mode, mixing it with helium is needed to get visible output. Red he-ne lasers are the most...

Hello to everybody, I am a laser hobbiist from Ukraine. I don't know wether this laser project is unique or not (probably for the states of former USSR it IS unique, we have very few laser hobbiists here), but I didn't find any information on anything similar. Most of people who worked with...
