Hello

[Erdem]

i love to burn stuff *evilface
what ill do : what people think = evil scientist - reality = YAY I POP BALLOONS

 

[Erdem]

and also if yellow and red are both barely visible and expensive why would anyone buy whats special about em ?

On every post you make there is an edit button. This forum likes it when you edit your posts rather than double posting.

Burning power is determined by the beam diameter and mW power level. a 500mW violet laser with a 2mm beam will burn just as well as any other color with 500mW and a 2mm beam. I guess violet and blue would burn just slightly better, as the shorter wavelength is more energetic, but at equal mW I wouldnt expect to notice a difference.

Red is dimmer than other colors, other than violet, but that doesnt mean it is not bright. If I were to show someone my 638nm laser, they would probably say it was the brightest laser they had ever seen, until I pull out the 445 or 532

Asking why someone would want these colors is like asking why someone's favorite color is not the same as yours

Red lasers are not particularly expensive, though yellow ones are even more than greens

 

[Erdem]

so the nm just differs colour and visibility and mw differs visibility and burning power . so 1.5 w 445 is safer . Is 445 al lil bit dim in daytime or normal ? because green is very shiny in day time too

 

[Shakenawake]

It's possible depending on lighting, but green is indeed the top color for visibility in the day time

Sorry , from now on I will ! Also I want to buy a blue laser that can be seen easily and brightly in daylight . What power should it be and what laser which company do you recommend . Although i know there arent any 'beautiful' laser cases except WL and it oesnt really matter but is there a laser product known to have better looks ?

 

[Gun]

I'm no expert on purchasing lasers but some good suppliers are Lazerer, Laserbtb, CNI Lasers, O-Like, Laserglow, Optronics and Dragon Lasers. I'm probably missing a couple of good companies there. Blue lasers don't come in very low power, they normally come in about 1W.

 

[Shakenawake]

Even the beam of my 700mW green was not visible in direct sunlight, only when it was overcast, and then only barely. the dot is certainly visible. The highest power of 445nm you will find from a company is 2W, barely. for the beam to be visible in the daytime, you will need as much power as possible, even then I doubt it could be seen in sunlight. There are builders on this forum that can make 445nm lasers stronger than 2W, they are a little expensive, but often cheaper and of higher quality than ones from companies. I got my two 445nm here:Spartan BW Series 1 watt Blue Handheld Laser Pointer | Dragon Lasers
and here:RIFLE 445nm V2 - 1W Focusable Blue Laser Pointer

I got these before I knew of this forum, had I joined first, I'd have bought a 445 from a builder

I can't overstate the importance of safety and responsibility with any laser, irresponsibility reflects badly on us all

 

[Erdem]

For example how much would a fine ( idk what qualities it needs to have i will learn it ) high quality 2w 445nm laser cost from builders you mentioned ?

 

[Shakenawake]

I don't want to say who the builder was until I have his permission to do so. I will be getting a 3W+ build from him in the near future, it will cost over $450, but it is fancy with a massive copper heat sink that alone costs $80. A 2W should be obtainable for considerably less, probably half, certainly less than WL's best Arctic model.

So really the price depends on how nice you want it to be. More heat sinking=longer duty cycles=more $. There are a few other factors in price too. G2 lenses are better for burning and cost more but have poorer beam quality than 3 element glass lenses. some lenses can't be used after a certain power level. So many factors, my point is you can spend a lot or not so much, depending on what you want. My best advice is to learn as much as possible before deciding

 

[Erdem]

That price is really good ! So i understand that there are many parts and many choices between them and its a very complicated thing to learn in few days . Heat sink means covering ? The body of laser ? and will it be 3w or 3.5 w because you said 3+w ? I am not sure ( Im a noob as u know ) but amaik lasers dont stay in power they change one second its 3.600 one second 3.300 right ? is that what you meant ? I can afford higher than the price you said , also just because of curiosity i ask , is the covering nice looking ? Not cos it matters but ofc it makes you feel good if its beautiful U said lenses can i change lenses or is it built in ? ( ty for your patience and answers )

 

[Shakenawake]

The body of the laser is referred to as the "host". You would say WL Lasers have fancy hosts. Heat sinking refers to the lasers ability to dissipate heat from the diode. If a laser diode is not cooled off as it heats up, it will burn out, ruining your laser. The heat sink is the part surrounding the diode. On some lasers it is partially visible, but many have it encased within the laser host.

most lasers have lenses that are pretty easy to replace, or even switch out for another. Many of mine have this ability. 445 lasers have stable outputs, they typically peak quickly, then slowly loose power as battery discharges and diode heats up. to achieve full power again, it must cool off and have full batteries. Most laser wavelengths have this pattern of power output. DPSS (Diode Pumped Solid State) lasers have unstable outputs. 532nm (green) lasers are DPSS. They are far less energy efficient. Really DPSS is a whole other subject I could write more about, but it is pointless unless you plan to get one, as 445nm lasers are not DPSS.

I don't know exactly how much power the one I plan to get will have, only that it will be at least 3W, probably more. Every diode is a little different, even two of the same make and rating will be. there are freakishly good ones and duds alike

 

[Erdem]

Idk how lasers work and parts and diodes- I will learn . So can i contact with your builder can you please ask him/her if you can help me contact her / him ? Also , what accesories are required / good for owning a laser ?

 

[Shakenawake]

I have not heard from him yet. He will reply within a day. I might add that I would buy either of the lasers I gave you links to before I got an arctic from WL. The link I gave you to Lazerer's site was for the 1W version, they used to have 1500mW (1.5W) which is the one I got.

Really the only thing you need is safety glasses and good rechargeable batteries, and a good charger. There are lots of Chinese companies, some good some not, that supply cheap chargers and batteries. I would almost always recommend getting both batteries and charger from a battery site, rather than with the laser.

Safety glasses are the most important. Especially if you plan to get any laser 1W or more. Technically you need them for any laser over 5mW. As I said, the beam can be viewed without them, but the dot, and burning with a focused beam in particular, require their use. Some glasses protect against one wavelength, but not others. When you buy glasses, look at their specs. They will list an OD (Optical Density) rating for different wavelengths. Get one with the highest possible OD rating for the wavelength you will be using. Something like these I recommend:http://www.survivallaser.com/Safety/cat556089_826120.aspx

Tbh i didnt get a word from that sentence . Did you mean dont buy arctic buy one of the ones i sent link of ? Im not gonna buy arctic.
