$69.95

This listing is for New Old Stock High Power Laser Optics Crystals Assembly manufactured by VLOC company consisting of neodym vanadate, Cristal Laser KTP second harmonic crystal and system of HR mirror and output coupler deposited onto crystals sides.In more details the assemblyconsists of Optically Contacted Neodym Vanadate Nd:YVO4 (2,75% Nd+++) laser crystal and Second Harmonic Green KTPNon-linear OpticalCrystal(5x5x2mm size) cut to generate the second harmonicof YAG:Nd 1064nm main lasing line.Potassium Titanyl Phosphatecrystal is cut for NCPM (non-critical phase matching)532nm (Theta = 90deg, Phi = 23,5deg).

Optically contactedcrystalsare usedfor higher power lasers unlike glue contacted crystals where theglue is burning under intense irradiation power. The crystal assembly is rated upto 0.5W of power for continuous green 532nm line depending on cooling efficiency.Theoutput power of green light for this assembly depends on efficiency of cooling and pumping power. One way to get a good power is to use a thin Indium foil with small pinhole (about 1mm in diameter) as the heat conductor and to mount the vanadate crystal tothemetal heat spreader directly without intermediate substrate.I will include a small piece of Indium foil for free with this crystal assembly.

The other way to increase the maximum output power of crystal stack is to mount vanadate crystal in a way that it should be attached to some optically transparent heat conductive substrate like quartz glass, sapphire etc.and then attached to the metal heat spreader like shown on the last picture (commercial laser assembly).We managed to get about 350mW of green power with 2.7W of 808nm pumping power (quartz mounting substrate) and more than 520mW with 3.9W of pumping power (sapphire substrate). The other types of transparent substrates may be used like GaN, garnets, optical ceramics etc.


Please ask questionsbefore offerding.Due to the nature of product it is sold as is with no return!

Worldwide expedited shipping is $9.95. Payment is due within 3 days.

Buyer is responsible for all local taxes and customs fees whenever applicable.

Please note: the listing is for crystals assembly and indium foilonly! All other auxiliary items shownat the pictures (heat spreader and pumping laser) are for demonstration purposes and NOT INCLUDED with this lot.
