First impressions. (Laserhead)



1. It’s easy to mount.
2. it’s not to big but provides more then enough cooling for the diode
3. And it’s easy to replace the diode’s in case it ever dies
4. There are 2 diodes in the case and one pbs cube
Beam specs seem to be around 1,2 mrad
And the beam diameter is 4.5 - 5 mm
Beam quality is great no distortions or reflections. :



The focus of this module can not be changed.
This is because both diodes are mounted very close to the pbs cube.
So u cant reach the focus adjust ring
but this should not be needed normaly


And there are more than enough mounting holes on the bottom side of the laser head.

First impressions. (Driver) or in this case drivers since it has 2 of them


This driver was designed very wel.
The output is rock solid.
Ive not been able to find any spikes in its output even during blanking.
The current for these specific diode’s was set at 180 mA. Per diode.
The blanking input can handle up to 20khz. Ttl only
This should be more than enough for most applications.
Now for the output power
All power readings where done using a coherent lasercheck set to 655nm

The module is rated for 200 mw 650 - 655 nm
My first measurement just after power on peaked at 222 mw.





After 15 minutes I took a other measurement this one came in at 210 mw
After 1 hour I took a other measurement at this point the module was about 23 degrees.
And was stil doing  212 mw
Also this module it not tec cooled  the housing provides more then enough cooling for the two diodes..
Overall this module seems to perform very well.
Its output is stable and free of distortions and reflections
The driver is small and works perfectly.
Shipping to Europe took about 4 days
So overall I would recommend this module to anyone
Who wants to build a laser projector on a budget.
I’m not sure if this module is available in a higher power version
But im pretty sure its easy to replace the diodes with 2x 200 mw giving about 350 mw total
Hope this review was helpful

I'm surprised they are combining two lasers using a PBS cube for only 200mW. This probably has a lot of potential.

Yes i already emailed them asking if there is a higher power version.
i would have put in 2 x 200 -250 mw open can diodes to get 350-400 mw.
but can do that in the future ofcourse

How much does this thing cost?

I thought that driver looked familiar - same style used by Shinp in their dual 100mW systems. The pic is of the (2) diode mounts, is it the same as the mounts used in this Labbie?

the labby looks diferent inside.
it has 1 mount that holds both the diodes modules and the pbs cube

do it now do it now!!!!

if it's not broken, fix it till it is! :-/

already did
after tweaking the org diodes it did 250 mw
but with 2 loc's in there is doing 448 and havent pushed them to the max yet

I'm guessing it doesn't burn well, since it's not focusable?

it burns just fine the bare beam is enouch to burn very well
but ofcourse if u want to focus it even beter u can use a external lens

Still havn't answered how much the thing costs.

Wel lets just say its very compettative and less then your thinking ;D

Please contact Betty at Lanling  @  sales@lanlingtech.com

Tel her Martijn send u

She wil make u a great offer.

have an inside pic? depending on the price, this could be interesting for other diodes as well. a pbs will combine 405nm just the same. pics please!

yep got some
just send me a email and ill send them to u dont have the possibility to post them here at work
but these modules are very afforable

thank you for the fast response and the pics! i resized them and post what i got:

manuel

second one:

it looks very compact! obviously they mounted the diodes first, then adjusted the pbs and glued it in. so replacing the diodes could result in misaligned and non-overlapping beams, depending on how and how precise the die is oriented in the diodecan. so for me, this module would only be interesting for "harvesting" the pbs. for that it would be too small and surely too expensive, and what a waste too!
thank you for the insides, always interesting to see how professionally designed and manufactured thingies look!
