New SI Version works with the Safety Interface Board!

This is the new platform

7th Generation Product – 12 Years in the Making


At J Tech Photonics, we have been designing and developing efficient high-power diode lasers for a variety of applications for over 12 years.  We introduced the idea of putting a laser on a 3D printer in 2010 and a CNC machine shortly after this.  Whether you want to cut various woods, cut foam and acrylics, or laser engrave a variety of materials, we can provide the perfect laser for your project.


Combining Two PRO Laser Diodes – Maximizing Power


We have taken our popular 7W PRO laser diode and combined them into the same package.  Beam combining optics join the two laser diodes by polarization to get two beams out of the laser instead of just one.  Each diode has special optical elements in the diodes to also make the beam profile square instead of a rectangle.  This allows for higher precision for engraving and higher beam density for cutting.



More Cutting Power – Air Assist


The new Dual PRO laser has the ability to cut more materials at larger thickness than the existing 7W PRO laser.  While it can cut some materials, the 24W and the 44W lasers are much better at cutting.

Use of the Safety Interface Board

The new SI 14W version comes standard with the new SI board, allowing you to upgrade to the 24W or 44W laser in the future with just purchasing the laser head.  No need to purchase new drivers for each laser.




Engrave Photos Effortlessly

The 14W laser allows you to engrave photos at higher speeds than the 7W laser can.  Get super fine detail engravings with easy set up at high speeds above 100 inches per minute.

Engrave your favorite logo or design and then cut it out with the laser.  Super easy to make coaster and ornaments for family, friends, or customers.

Driver Overview

We have kept all of the features that make this laser kit awesome – precision laser trimmed regulators for constant current to the laser, 0.01 tuning resolution, digital isolation, soft start, esd protection, current limiting, and the list goes on.  But NOW we have more safety in mind as well!  The US Federal Government has a list of things that are required for operating these high power class 4 lasers.  They might seem trivial, but they could save your eyesight!  Here is a run down of the safety features to protect yourself and others:

  • Key Switch – This key is needed to enable the laser.  When the key switch is turned on, the laser is enabled and the key CANNOT come out.  You can only remove the key when it is disabled.  This feature is good if you have curious children or have your laser in a shared area and want to limit use.  Just take the key out and hide it!
  • Remote Interlocks – This feature allows for addition of switches to your enclosure so when it is open, the laser will automatically turn off.  Also provides for the addition of an E Stop button for the laser, which is always good for if you need to stop the laser super quick!  Add as many switches as you want to make a super safe area for your laser machine so nobody can accidentally look into the laser.
  • Power Fault Protection – This one may seem like it is not needed, but hear us out.  Consider your power goes out in your area where the laser is located.  You were running your program and then everything is dark…  Power doesn’t come back on for awhile… long enough for you to forget that the laser was left ON!  You come back and are checking your laser and boom, the power is back on, right when you are looking straight at it.  Well, don’t worry because the laser will be disabled whenever the power to the driver is lost.  Press the reset button and you are back in action!
  • Emission Indicator –  The small little LED on the front to let you know  your really super bright laser is on…  They require this in case you are using an infrared invisible laser.

This is the 7th generation of the popular High Current Laser Diode Driver series.  We designed this new generation to follow the federal guidelines for safety compliance for high power Class 4 laser operation.  This includes the use of a key enable switch, safety interlock system, power off reset, and laser LED indicators.  All of these features make for a safer laser operation and will comply with federal laws regulating such operations.

At the heart of the product is a semiconductor controlled mosfet inductive current circuit giving extreme efficiency and high voltage that the dual laser needs. Couple this with inherent safety features like soft starting, current isolation, reverse protection, ESD protection, and thermal shutdown control and you have all you need in a small package.

The high power laser diode driver is cost effective and easily integrated into industrial, research, or enthusiast projects and products.  The driver can be operated in CW mode or in Input Control Mode to be interfaced to remote electronics.  This design uses digital isolators for super fast response and input range while protecting the laser from deadly ground loops.   The board has screw terminal connections as well as Molex mini-fit Jr. connectors for easy connections to external equipment for control and the laser diode output.
