Laser Vacuum Chamber Laser Chamber for Educational Purposes Laser Burnt Wood Laser Warped Plexiglass

The lasers on this page are fully assembled but untested. They are research lasers obtained from the estate of Peter Chenousky. His company Q-Source designed lasers for other researchers, NASA, the U.S. Navy, and many other commercial interests. Some lasers are still sealed and may yet contain a vacuum and/or inert gases. We have no idea as to the mixture ratios of any gas, but Helium, Xenon, CO2 were known to be used. We have not attempted to match any of the power amplifiers with any particular laser. We do know that much of the frequency generation and amplification equipment was reused to supply output to multiple lasers. Laser power ranged from several watts in the smaller lasers to hundreds of watts in case of the larger lasers. Some of the equipment is in the 1KW laser output range, some devices are not lasers themselves, but are optical amplifier devices to strengthen an already generated laser beam. All the output wavelengths are in the infrared range. Buyer assumes all risks associated with powering and using these devices. These are NOT commercial products, they ARE DANGEROUS; we assume the buyer has extensive knowledge in the laser field and these devices will be used as research devices; saving the tooling costs of creating vacuum chambers and mirror mounting end walls/caps. Lasers are not returnable.
Q-Source Double Research Laser
Q-Source Double Research Laser
(LZR) RL3375
19-1/2"L x 3"sq chamber "MO" and +14.25"L x 3"sq chamber "HYBRID" on a single base. This was another set of lasers used in their NASA research project. Some of their research was in laser amplifiers where an existing laser is amplified in another device. Is that what the "HYBRID" chamber of this laser does?
785 Watt Research Laser
Q Source 785 Watt Research Laser
(LZR) RL6350
63"L x 5"DIA chamber, 4.52"I.D. This laser was found without the end walls mounted and with hand printed results on the outside. 1,000 watts of power in and a 785 watt beam output (?). We found some round end walls which fit and have lens mounts that match the area of the plasma discharge track. The mirror mounts hold a 1.5"DIA mirror with o-ring screws on caps.
Q-Source Research Laser
Q Source Research Laser with RF Box
(LZR) RL3203
32"L x 3"sq chamber, 44"L x 6"W x 10"H overall. Single rounded electrode rail on bottom of plasma discharge area. Surrounded by alumina ceramic on 3 sides. A 95% 2MCC mirror on one end and a polycarbonate window on the other. Two 1000pF 5KV doorknob capacitors are attached to one electrode feed through, 2 air variable capacitors, one 140pF doorknob, and a 1µF 4KV oil capacitor are visible in the matching network RF box mounted to the top of the vacuum chamber. Unknown working state as some wires appear disconnected.

Q-Source Research Laser

Assembled Research Laser
(LZR) RL2201
We have little info on output power, mirror specifications, or inner design specifications. We did find the specs for the matching network design (including in PDF). This was the "LO" laser used in their NASA research project. 16"L x 8"H x 6"W overall.
Q-Source Research Laser
Assembled Laser with ZnSe Window
(LZR) RL1210
This one has an unknown output coupler mirror on one end, likely a ZnSe window on the rear. There is an adjustable reflector mounted on a 45° brewers window with a sensor mounted behind. This external to chamber mount has a 5-1/2" adjustment rail. Most likely for testing mirror focal lengths. The vacuum chamber itself is 5"L x 3" sq. Unknown gas or vacuum mixture. Both ends have an output sensor consisting of a series of alternating (cathode and anode) insulated discs, where the beam travels through the center. 16"L x 8-3/4"W x 7"H overall.

Q-Source Research Laser

Laser with 2 Air Variable Capacitors
(LZR) RL201
This laser has two air variable capacitors between an inductance coil on the input matching network. Unknown total reflector, output coupler mirrors, or gas ratios (could be CO2, He, Xe or vacuum). Laser vacuum chamber outer dimensions are 5-1/8" x 3" sq. 9"L x 11"W x 7"H overall.

Q-Source Research Laser Kit

Research Laser Kits
(LZR) RL102K
The current configuration of this 6"L x 3" square laser body is with two 0.6" thick plexiglass viewing windows. It also has a 1/4" brass compression fitting attached. Inside it has a set of electrodes and plastic insulating blocks; ready for turning a gas of your choice in to plasma. We are also including a set of end caps like (LZR) HRM-OCM-3. Because this is a round bore chamber, it does not require the square end walls. The end caps are this chambers end walls. We are also including an extra chamber body as we do not have another top cap of this type. Finally, there are two external caps which would typically hold a laser sensing device (not included) as shown in the images.
Q-Source Research Laser
Solid Aluminum Research Laser
(LZR) RL101
The research laser that started it all. 4"L x 3" sq solid aluminum with a 2.25" bore through lengthwise. (12) 8 - 32nd threaded bolt mounts for end walls. Includes 2 end walls with 4 point adjustable mirror mounts and mirror mounts for 1/2" diameter mirrors (which screw on with O-rings). Side port accepts a 1/4" nipple for vacuum and gas injection. Inside there is a plastic insulator with embedded electrode connected to the conductor of the BNC feed thru at the top of the chamber. Two pieces of Alumina ceramic are positioned to create a rectangular region for plasma discharge; a particular shape which was the genesis for one of Peter Chenousky's ( Q Source President) numerous patents. An opposing wedge clamp is used as the bottom electrode (tied to chamber body) and to hold the entire assembly in place. No mirrors or lenses were left in this laser chamber, but a large variety are available here.
Q-Source Research Laser
Internal Circuitry High Power Laser
(LZR) RL1916
As their laser design evolved, the capacitor and inductor matching circuitry was integrated internally and the power of the laser increased. Also a switch from plastic to alumina ceramic was made to dissipate heat. This 19-1/2"L x 3"W x 4"H laser appears to have ceramic inside - looking in the gas port hole - which is no longer plugged. A note on each endwall states the total reflector is 2 mcc, Si material; and the output coupler is 90% reflective, 2 mcc. Unknown internal design or layout.
Q-Source Research Laser
Internal Capacitor Inductor Network High Power Laser
(LZR) RL1999
Like (LZR) RL1916, the capacitor inductor network is internal. This laser still has 1/4" vacuum piping and valve intact. Unknown total reflector and output coupler specifications. Newer style end cap design.

Accepts the following end caps:
Q-Source Research Laser
Sealed Laser Chamber with Plexiglass End Walls
(LZR) RL1643
16-7/16"L x 2-15/16" sq with a 2.20" radius bore through the center. Two pieces of alumina are wedged together to form what appears to be a 1/4" diameter discharge area. Not sure if any point of the alumina provides an electrode path - i.e. an embedded electrode - or if the discharge is great enough to pass through the thin walls at the top and bottom of the alumina walls. The chamber is sealed off with plexiglass end walls. Unknown vacuum / gas status. The device must have been successful because "patent pending" is hand written on the side - most likely by Peter himself.

We're going to include 2 end walls which have a round bore o-ring seal groove on the rear and ports that appear to line up with the center of the discharge area. One end cap will accept (LZR) ENDCAP-7, the other one has threaded bolt holes that do not match any other end caps we have.
