Hi, ok.....good to know.......in some other situations meens Duty-cycle the frequency :whistle: And......it`s a Full-Time-Laser :drool::drool::drool: .....An hour ago i used this Laser for branding a picture on wood...... 45 min. non-stop ;) ...but we have here at the moment about 38°C and the...

Hi crazyspaz, sorry, i can`t find any informations about duty-cycle on the Datasheet and the websuite of the producer...... maybe 150KHz......but not sure. A1W Bestückung Entwicklung Fertigung- Professionelle Elektronik ( HKO1500 ) I`m not Profesional with Electronic.....the mechanical side...

4 Weeks ago i changed the Driver to a fixed one with 1500mA without Poti ...... and he burns burns burns in wonderful blue :drool: ok....thats enough :san:

Here more Pics

Hi All, here now my, at the moment, strongest Selfmade Laser with aktiv cooling system :beer: For the Housing i used a full Aluminium Hand-Gas-Pump which used in the industry to locate dangerous chemicals in low concentration. The M140 LD is mounted in a cooper Heatsink with the M9x0,5 Fine...

The runtime is ok.....20 - 30 min., after a time between 5-10 min. i make a brake, because it`s better for the small 16340 Batterys..... the Laser is warm but not hot. The better way are the 18650 Batterys, but i don`t want to change the hole construction. On the bottom there is a separat...

Hi again, here the second conversion in a diverent way. The Laserdiode stays fix and the Collimator with three-lenses is moving to fokus. The Driver needs a input Voltage between 7-9Volt and the Output current is 1000mA. The Heatsink ist at my works everytime copper, but here with aktiv cooling...

Hi, i want to show you my first Flashlight conversion to 1W 445nm Blue Laser with passive cooling. I use a round Step-up-Driver with a current of 1250mA@5,1V (Voltage not sure) with one 18650 LiIon-Battery. The Collimator is a three-Lens and is fixed in a Aluminium-part. The Laserdiode is...

Hi, @Mattronium yes...Heatsink is enough :D ........and yes, all Metallwork is selfmade in my little Workshop. The Diode is from a Apple-DVD-Drive GA32N 678-0603C, Open Can 3,8mm and i found no Datasheet about the used LD......so i think it is a 635nm...i`m not sure. Here some Pics from my...

No Problem..... i have found the Drive-Name : " LG BluRay Brenner Laufwerk BH10LS30 " Raveman

For the Diode i have no Informations, but the Driver you can find on Insaneware Deluxe ....but he is to large for inserting into a Aixiz-Modul. For me no problem because the Aixiz-Moduls are...... only my mind....too bad for heatsink. I use only copper for the Diodes :whistle: Raveman

Hi Laser-Freaks, here i will show you my seconde Laser-Project with Red Open Can Laserdiode with 3,8mm size from a 20x DVD-Multiread-Dive......allso bought by ebay..... each for 1$ :D:D:D The Current is about 300mA @ 3,1V and is burning in wood and flash matches on short distance...

Thankx, i think allso......in my workshop i have a big sampling of Metal-Part who are waiting to use for constructions.....thats my way. At the next i will posting my first Red Laser :D Raveman

The Driver is for a input of 5V to 9V and has a various Current to 500mA. He can used for Red and Blue Laser-Diodes. I use a LiPo-Battery with 7,4V and the Current for the BlueRay-Diode is fixed to 300mA. There is no switch mounted so the Laser and the fan is starting directly then the Battery...

Here the seconde part: at the next I have the fan and copper diodes recording used finally i soldered the the LD-Driver ....and at the End i insert the Collimator and set the Laser into a Holder .....and the Laser was ready to burn :beer: Raveman
