功率 - Power Output 撕毁无效 - If torn, all warranties are off 编号 - Serial Number What I surmise from this informations is that there is a seam under the label. In order to get to the diode, you need to open the module. Doing this will in some way tear the paper label. (thats why its there, its to...

Hello Haiyder, First of all I would suggest you first make a post introducing yourself. Second I would like to say that you should do a bit more research on how lasers work before asking for help. A simple understanding of how drivers work, why they are important should suffice. Also there is a...

Hi, I would be glad to help because I live in China and speak and read Chinese. Would you mind posting a few more photos of the text? Thanks

I just completed my Osram 445nm Laser. It is in a heat sink with a fan and should last a while. The stand, heat sink and fan cost 7$, the diode itself cost 30$, the housing cost 1.5$ and lens cost 6$ (Probably got ripped off). Anyway here are some photos: Power source: Pictures of laser...

你好，我也是中国来的激光爱好者。终于看见了一个从中国来的用户。:) 你有淘宝店吗？

Thanks for the reply :)

Thanks for the reply, I will try that :) :thanks: Anyone else have an answer?

So my first Osram 445nm 450nm 1.6W PLTB450B diode that I bought off a website arrived today. I have yet to open the box because I am worried about shocking the diode. The first 250mw 650nm red laser that I built was before I started reading this forum. I did not use any ESD precautions except...

WOW!!! you are the most helpful member ever :) Thanks for the reply and good day to you :) :thanks::thanks::thanks:

Thanks for the reply DTR :) According to the data sheet it says in order for it to run at 1.6W it needs 4.8V. From what I understand from your post is that 4.8 should be the voltage drop I will be aiming for with my test load. Am I correct? :thanks: If I am wrong, would you mind telling me what...

This is probably the worlds most noob question, what is the voltage drop of the diode? Is that the same as operating voltage (Ie. 4.8v) Sorry for the noob question

I don't know what a first and second range is... I'm assuming it is when the driver increases the voltage by a certain amount the first range and a second amount for the second range. That was just plain old guessing...lol. The description says that this driver is used to bring a 3.7 volt 18650...

Also I have another question, do you have a link to a thread that teaches about how to calibrate/set driver circuits can how to make and use a test load?

Thanks for the quick reply again. I will use the first driver then. I will set it to 1.2 amps and hope for the best. I really hope a one inch by one inch heat sink with a 12mm hole down the middle will be enough to dissipate the heat and keep it below 40 degrees C. The problem is that I live in...

Thanks for the quick reply. I wasn't actually planning a host, I want to put it in a 1 inch by 1 inch aluminium heat sink since I didn't want this one to be portable. The driver well...I have no idea what are the specific driver specs (stupid Chinese website) Because i don't actually know which...

I have recently stumbled over a good deal on the Osram PLTB450B 1.6W laser diode. The price of these things seem to be cheaper than other laser diodes of the same colour so I did some research on it. I found this thread on this forum with the diode being tested. 1.6W should be a good burner...

I am a ABC (american born chinese) I moved to China when I was 6 and have been going to an international school ever since. I plan on attending high school in america. Hopefully Exeter :)

Thanks for the quick reply!!! :)

Hi Svenvbins!!! Thank you for you post, but I have a question about calibration. (I know this is probably answered somewhere else but I am new to using a search function and can't find any info.) I already know how to build the test load, but what is the mA to mW ratio? Because from what I...

I will take safety very seriously, in fact my 2 pairs of Eagle Pair goggles are already on the way. One is rated for 190-470nm&610-760, with OD4+ as well as a light permeability of 40%. I was hoping to use that one against the red laser and violet/blue laser. I also ordered a pair 200-540nm...
