LaserWave product review by Daedal

[Sandyaser]

LOL they are not off to a good start. Just sent them an email and got this back:

Sandy@laser-wave.com
   It appears that the DNS operator for laser-wave.com
has installed an invalid MX record with an IP address
instead of a domain name on the right hand side.

That is their main sales email address on their website!!


*** Edit *** Same message for this email address marketing@laser-wave.com
Does not bode well if you can't contact them. oh well at least I tried.

dear xgeek,
Thank you very much for you attention. and i should say sorry to you about the website error. our website is reconstructing recently,so maybe occur some problems. plz understand, and it will be fine next week.

if you had some questions, plz contact with me via laserwave@163.com.

and thanks very much to DDL. we will supply big support to everyone here, no matter purchase our product or not..

Sandy

hiya,my floks, the website mail system occur some problems indeed. sorry about them.plz contact with laserwave via laserwave@163.com , my colleagues and i will give feedback as soon as we can. and the website will be fine next week. sorry for any inconvenient.

and it's 19:10 Beijing time. i 'll finished today's week.

happy weekend,dear all.

Sandy

Hi XG,
Don't worry about that ,there is also review about our lasers:http://www.photonlexicon.com/forums/showthread.php?t=3248, in PL forums, and here is the group buy of our other products,http://www.photonlexicon.com/forums/showthread.php?t=3009,(this products also group buy in this forums) as you know ,forums is the disscuss area, if our laser not well ,all the people will know soon, and maybe will not buy our products later,we don't want this happen, so if someone had the brave to sell their products on forums, their products must recieve strict test, if our lasers work well ,why not got one,only you got one and test it ,you will believe, what products we build.
I am sure ,all of you will be luck.
Best regards!

Thanks for the review. The only thing I worry about with reviews like this is that they will send you their best lasers that are over spec to make them look good.  There was no chance of them sending you under spec lasers knowing you would review them.

Us punters may not be so lucky.

i sent them a message on their site rather than a direct e-mail, and i got an email back the next day with 4 different spreadsheets with all of their prices listed. Very pleased with the immediate reponse and the prices look pretty good, especially when their units preform as they did for Daedal here. However, I think they sent me a Euro spreadsheet for the 635 nm because it seems WAAAY too cheap. All of the others were USDollars, and the 635 says USD in the title but Euro in the column for price...

oh well, looks promising, maybe Daedal could hook us all up with a special LPF discount for laserwave ;D

dear Dough..

sorry about the mistake of the quotation spreadsheet.and i already send you a correction via email.

cheers!

Hi Dudes!

I must say the laser-wave modules perform great!!
And they are overpowered
My greenie 300mW is above 430mW and my Blue 100mW is doing above 130mW
The quality of the beam is damn nice too!!

And they are very professional
Top notch service! My next laser modules I will buy from Laser-wave!!

 

[Sandyaser]

dear guys, we attending to the ILOPE-EXPO in Beijing these days, which is an international professional fair of optoelectronics industy all over the world. i'll upload some photos about this expo later in order to share with my floks here.

good regards.

Nice review. I'm looking forward to seeing the results of a test with an IR filter though as that can make all the difference when using a silicon-sensor.

Hi Carter,
You took the words right out of my mouth, so now I don't need type them

Dae...

How Long will you have the lasers to be able to finish the tests you had planned??

[Daedal]

Not sure Larry... I'm probably going to finish most of it all up tonight. Turkey and preparation for it, along with all the work-related stuff due to this vacation was a bit of a hold-up.

Not sure how long they will stay here... :-?

Hi DDL
I am sorry but all the guys are waiting for your review.
I know, these days is thankgiving day, and later will be Christmas day, :'(,I am sorry, at these days I still desire you to quickly finished the test.
Wish you will finished soon.
waiting, waiting, day and night.
Best regards!

Just wondering:

From my experience working with TE cooled laser modules, the graphs presented looked like these lasers had a very high value for RMS stability. Was the RMS stability measured, and did it match the specifications? At the very least it should measure under 10% RMS, and most of our scientific and industrial customers demand <5% or better. Was there any mention of RMS stability in the specs?

 

[Daedal]

I tested for IR emissions and found NOTHING! The IR protection is perfect. The measure on a thermal head and on a silicon sensor was dead on (bar some variance due to power fluctuation).

As about the Dichros, I tested transmittance and reflectivity on both green and blue. The reflectivity on blue was phenomenal! Out of a measured 115mW reflected (114.7mW actual) only 0.7mW were passed through (0.673mW actual) at 45 degrees. As for the green transmittance, it wasn't that great as bridge also told me the one I have is not the best one they can make... it passed 360mW and reflected 48mW at 45 degrees... :-?

Overall expect to have this whole thing done very soon. There will be pictures of the mixed color. Although, I have to note that the lasers didn't hit on the same plane exactly, and would probably need a little bit of fiddling to get them on top of each other perfectly...

we had do IR filter coating on the mirror, , so we didn't need IR filter like others

"I tested for IR emissions and found NOTHING! The IR protection is perfect. The measure on a thermal head and on a silicon sensor was dead on (bar some variance due to power fluctuation)."

Yes, the Dichroic didn't coating AR , if we did AR coating ,sure they will transmittion more green power, we actually only consider high reflection of blue, as you know,blue is expensive ,and blue high power is some difficult, but green is cheaper and can do bigger power. Yes, I am sure next time will be better. the green will be pass more

"As about the Dichros, I tested transmittance and reflectivity on both green and blue. The reflectivity on blue was phenomenal!

Hi, DDL, if you used the laser I give you ,you can't got perfect color laser, because the green is high but the blue is low,wish to see what color you will got, that will be interesting.yes, the blue laser beam height from base is 29mm, the green beam height from base is 24.8mm, so they don't hit on the same plane exactly, I 'd like to know if all of you like the same height, if that answer is sure and don't mind a little bigger sizes just like blue, next time we will do the same sizes, the same beam height. tell me all you want, we will consider you convenient use,and change it for you.

Thank you for chiming in bridge

I'm sure combining the colors will not be the right ratio, and I wasn't worried about that... ;D

Hi DDL,
Thks very much for you help.
How long did you need to finished the test ? TTL, Analog, etc, all of us are waiting
Best regards!
