I am looking for a non polarizing beam splitter. larger size if possible. can trade high voltage parts such as 10kv .005uf caps, high voltage 2 M Ohm resistors, lots of mosfets, schottkey diodes etc.

I have alot of new old stock capacitors what were given to me. they are superior to the cheap blue ones made by china as these probably were made in the usa or ussr way back when. here are the specs 10kv .0047uf resistor if for scale

it probably has something to due with the lasing material being square shaped on a die.

Which diode laser has the best beam quality. I am looking for TEM00. gaussian profile, color does not matter.

Do you have any more of these lamps? I have even better way of running these.

Drive that 50w laser diode with this Power Made Simple - ISL8225M put in a few li ion batts this power module 808nm diode array a ktp crystal optics bam you got your self a real 40w green laser to play with.

I have copied a schematic from the book " art of electronics" by Horowitz. I believe i have found a very easy to do laser diode driver. Its from page 76. Current = Vbe/R2 VBE is found on the datasheet of your pnp pnp pair. Vbe is usually .65 volts load is the laser diode connections...

I am not really sure if these are pure enough for a n2 laser. But since the n2 laser is very powerful I am inclined to say yes. just be sure to use pure solvents

Here is a beam dump used by the department of defense. buy a stack of razor blades, bolt them together so that there is a surface of many edges. take that to a candle and soot up the blades. The soot absorbs the light and the razor blades act as a almost perfect blackbody.

I have some really high quality fluorescent dyes for sale. Perfect for your 405, 445, 532nm lasers. I have red fluorescent dye, green and blue. You can put the dyes in plastic bottles and tubing or put in water fountains. The possibilities are endless. A tiny amount goes a long way. One gram...

shouldn't we stay on the topic of the possibility of getting a really high powered diode in the near future and what ramifications it involve>

Does anybody realize the potential that phase change materials represent with cooling laser diodes? think. a small block 1 inch square can absorb 5 Whr I am trying to put up a group buy for some.

500 watts would be easily dissipated if phase change materials would be used for the heatsink. I put up a feeler in the group buys section. no bites yet. But soon electronic projectors and equipment will be using multiwatt laser diodes. Look the actual chip itself is smaller than a grain of sand.

I am so excited about the pace of laser technology. Do you think that we will have 100watt blue handheld lasers? could you imagine that?

Hi Guys, Can phase change materials make it easier to build even smaller laser housings and operate really powerful diodes with small heat sinks? I think the answer is yes. Wouldn't it be great to apply to cooling power of ice at room temperatures? A phase change material has a huge heat of...
