The diode is called GH05C01B9G. Is it 1 or 2 beams (I am looking for just a single beam)

I am looking to buy sharp 520nm 1200 mW. Is it single or dual beam. It is the cheapest 1w+diode I can find compared to nichia ndg 7075. It would be an optical nightmare to combine or collimate the 2 beams.

They are safer than 1w because lower hazard distance, and they do not burn skin or start fires

Yes, there are ways to see IR light such as laser. There are two options. Either a IR converted digital camera or night vision glasses/goggles binoculars. You can buy these from multiple sources online.

Hi, I have never built a DIY laser before but I do have experience with strong laser pointers, electronics, soldering and LEDS. I would like to build a green laser pointer from parts for as cheaply as possible. I know I need a host, diode, driver, module, heatsink and battery. For the diode I am...

As a first laser I would reccomend a weaker and more eye-safe laser rather than jumping straight into high powered laser which for many you need eye protection. As a first laser I would say you should stick within the class 2 or 3R laser safety rating which is 1-5 mW of power. These are usually...

Green Dpss lasers are usually 532nm whereas direct diode ones are around 520~525nm. Direct diode is much stronger than dpss so if you have a high powered 1w+green laser it's most likely direct diode. Green dpss lasers are usually below 500mw. If it's a cheap laser like the chinese built laser...
