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

Hi all, this is my first posting here and i want to show you the Pics from my first selfmade Laser with a Laser-Diode from a broken BlueRay-Drive i bought at ebay. Here you see the Housing i used for the Laser......it was a pneumatic cylinder at the next step I have made the fit for the...

@Elektroniker ..also gelernt habe ich mal "Maschinenschlosser" im Weltgrößten Chemiekonzern, der hier in Ludwigshafen seinen Stammsitz hat. Danach Weiterbildung bis zum Industriemeister Fachrichtung Chemie.....und arbeiten tue ich als Schichtmeister in der Produktion von SAN-Kunststoffen, d.h...

Hi, thank`s to all for the friendly welcome :wave: @Elektrotechniker ....gutes gelingen bei deinem Studium....... bist ja nicht soweit von mit entfernt. Raveman

Hi BaifSigurdso, i have read a lot about CNC engraving with laser. Very often they use CO²-Laser with more than 20W ..... like Laser Chick tell`s you. Even infrared lasers are often used with 3-5W and 909nm or higher.....but they are dangerous because the Laserbeam is invisible and goes deep...

Hi, thank`s for your regards.......and i`m sure, that i need your help in the next time. At the moment i want to upload a gallery of pics with all steps of the different varios of the heatsink, my first BlueRay 405nm with ??? maybe 250-300mW and a Red Open Can with 635nm and the same power (i...
