I recommend going to www.globalspec.com and typing "Laser" into the search box at the top and clicking 'search'. You will get a list of categories, select the first result "Lasers, All Types". At this point you will have to register. Once you do you will be presented with a list of companies that make lasers. The list has 469 companies. You can then filter the list from questions on the left. Some questions include color, wavelength, power, etc. This should get you to the product you're looking for.
Thank you for youre suggestion . i do it before but there isnt any catagory for my selection . I need a high power frequency-doubled Nd:YAG laser about 100 to 150 w output and with 532 nm wavelenght . but there isnt any catagory for this selection . can you help me.
Yes. The category you want is "solid state lasers". Go to www.globalspec.com, type in "solid state lasers", select the first category "solid state lasers". At this point you need to register or sign in. Now you're presented with a list of solid state laser manufacturers. Use the filter on the left to narrow the list. For lasing medium select Nd:YAG, that reduces the list to only manufacturers of Nd:YAG lasers. Next select the wavelength range 475nm to 700nm. This will reduce the list further.
If you did that, one of your results would be this:
Good Luck!!! I don't think anyone makes a DSPP laser in the green at 100 Watts! If they do, you'd better have a budget about the size of a small NATO country. You're talking really big money!!!
Also, why so much power at 532nm? What's the purpose?

I have visited your recommended site , do they build costomised lasers ,i am looking for metal itching , glass / crystal internal engraving ,apart from power (watts) , speed , working table (dimensions) are imp specs , i have seen and used lasers from USA ,TAIWAN ,CHINA , KOREA
For your application, it will need different type of laser.
For instance, metal itching, I would recommend fiber laser. As for glass and crystal, CO2 is the best laser for it. However, if you are saying internal engraving, if I am not wrong it need green laser to do the rengraving.
Thank you .if you can please send the spesifications of your lasers to choose from them. i want it for medical experiment and i need a power between 100 to 150 w and 532 nm.Best Regards.
I'm trying to build one using a Lee Laser diode pumped ND-YAG head, using either LBO or KTP crystals and a Q-Switch in an intra cavity resonator. Got the head working. Now have to mount components in a laser resonator assembly and align using IR viewer and external monitor for safety reasons.
100+ watts is a lot of 532 nm Nd:YAG laser power. Generally, this would be a custom manufactured laser and would be quite expensive. Hope you are prepared. Your reference as a medical experiment does not lend much for any of us in attempt to assist/suggest to you. However, I think you may have mentioned "speed", so I would then believe you are marking/etching. So, that likely leads to medical-related.
You need to further describe the application.
10W typically does well with applicable materials.
LaserLover has an answer in re: Lee Laser. I've seen the their ad before and questioned it. Let's not necessarily re-invent the proverbial "wheel".
Nd:YAG lamp-pumped technology is this. Begin with a lamp pump at 4250W, will result in a CW 1064nm power of about 100 watts or less. Add-in the 532nm multiplier crystal and you have a 10:1 conversion, or about 10 watts.
I will admit that there are seemingly certain improvements in diode pumping that reportedly can result in 532nm laser outputs that are better than lamp pumped systems. I wouldn't doubt that, in that I've had my own ideas of the technology.
Funny thing about physics: it tends to be absolute. Or are there aberations?
But then perhaps Lee Laser has a technology undiscovered by many others and they can achieve 1:1 IR to green light conversion with no loss. This would be a real discovery, and where we're back to 100% conversion efficiency.
There are so many of these on CR4; but then there is nothing wrong with teasing the mind. Tickling. Inspiration. New ideas.
The reason why you need so much xenon light is that most of it is wasted. In DPSS ND-YAG, the rod is pumped at the exact wavelength it wants: 808nm (causes lasing at 1064nm), which is much more efficient.

Further to the above comments about LEE Lasers 100 watt 532nm . They use an LBO non linear crystal cut at Brewster angles within the resonator with an oven to heat the crystal and eliminate walk off so they can acheive even higher efficiency and better stability. Most other DPSS designs use external SHG crystals with much lower efficiency.The HR mirror is 100% reflective at 1064 nm and 532 nm. The OC laser resonator mirror is 100% reflective at 1064 nm and partially reflective at 532nm, so all the pumping power stays within the laser resonator. Also the laser head is Q-Switched with maximum efficiency at 10 KHz but can run up to 50 KHz with lower power output. That's how Lee Laser get such high efficiency.
