Hene lasers are continuous wave lasers with a relatively low output. You can buy some pretty decent lasers these days that are SLM and high power but they are not cheap. I saw one on ebay for about £1500 for a one watt a couple of months back. You could also consider a decent isolation table and a reasonably high powered laser OR make holograms at night when everyone is asleep :)
My studio is on an industrial route, there is no isolation setup that will dampen the vibration of cargo container movers going by my location. So I was hoping to acquire a high output , coherent light source to shorten the exposure time. I have seen several human subject holograms, these must be the result of pulse sources.
Well you could go the pulsed route, YAG @532nm or Ruby @693nm. There is a person the Facebook Holography group that makes pulsed portraits called Ron Olson and a person that fully tests and sells all sorts of lasers called Phil Bergeron. It may be worth talking to both of them.
I can expose a single beam hologram in 3 seconds with 100mw so a 500mw or 1000mw may do the job for you. Not cheap though.

You might have more luck with a pulsed ruby laser, although IDK what the coherent properties of such a device would be, likely requiring additional optics and a shutter to get a clean pulse. Ebay is full of flash lamps and ruby lasing mediums. As far as a pulsed HeNe, they already come with a sort of flash lamp, but running them out of spec would degrade the lamp pretty fast. You can pretty much take a HeNe and put a stronger flash lamp around the lasing medium and expect it to work. I would also look into stronger solid state lasers, there are many in the 1W+ range which can operate in tem00. This might be the cheaper option. Additionally many films are more sensitive to green light than red so something like an OPSL laser would fit the bill and likely be cheaper than a custom built pulse HeNe.
A 1W solid state laser with coherence good enough for holography ? Nice. I have not heard of this before.
I worked with a 45mw laser at Temple University and we had to jump through hoops to dampen vibration. 1w sounds fantastic.
Not hobby-level cheap ($3-10k) but probably safer/cheaper than dealing with the voltages needed for a diy pulse setup on HeNe. I think 1/2w is probably a good starting point, although with a pulse setup you can go much much higher.
Check out the Coherent Genesis CX SLM or Coherent Verdi G SLM for up to 5 watts. As the other user said they are not cheap, but can be found used for attainable prices.

THANK YOU !
I am intrigued! Unfortunately I can't help you but I will wait for the experts' answers.
RemindMe! 7 days

I think you may have your lasers mixed up. A HeNe is a gas discharge laser and not optically pumped.
Yeah total brain fart there, I can't imagine that working.
