ND-YAG Laser & plete
Description : 24 Jun, 2023
For sale a plete solid state diode pumped (DPSSL) laser. The ponent is the diode pumped laser head, model LHD-20 ,made by Lee laser. The laser head has an hour meter that has less than 340 hours on the pump diodes so they almost as good as new head which sells for $21K USD. The laser head contain an ND-YAG rod lasing medium measuring 3 mm diameter x 108 mm long. A typical lifetime for these laser diodes should reach 8000 hours or more if you take good care of it. Also included is a water cooled laser diode driver made by Analog Modules ( model 770-163 which is a custom modified model 779) and 24 VDC switch mode power supply. You have to supply a 12 VDC power supply for the laser diode so I used a car battery if you want to drive it up to 30 amps. Also included is a TEC cooler made by Melcor, model MLA270DH2-115 high precision liquid cooler valued at $2850 USD in good working condition. Also included is a used water cooled laser q-switch made by Gooch & Housego, model QSD27-3C-K-L3, which requires 24 VDC and has built it driver so all you have to do is feed it a TTL signal (10 kHz optimal). Also included is a 650nM red laser diode and kinematic mount used to align your optics in the 1.2 meter long resonator made with Inconel metal ,precision support rods. Also included are an in resonator safety shutter and a four position variable aperture. The kinematic laser optics mounts contain 19 mm diameter HR and OC, ND-YAG optics of unknown parameters. I can include two ND-YAG laser guide/turning mirrors on mounts and another mounting plate for the q-switch. I can also include a water cooled LBO crystal and AR coated optics for intra cavity frequency conversion to 532nM (intra cavity conversion is more efficient). I have some support documentation that will also pany this package. The laser diode driver was tested with the laser head and was capable of providing 29 amps of CW current operation the last time is powered it up. I do not have collimating or focus optics which would be required plete this setup. The whole resonator assembly is mounted on a heavy duty aluminum base with channels to mount other optics and perforations for cables and hoses. Pickup only due to the delicate nature of ponents and I will not ship outside of Canada. Serious inquiries only.
