- Key Switch –\u00a0<\/strong>This key is needed to enable the laser. \u00a0When the key switch is turned on, the laser is enabled and the key CANNOT come out. \u00a0You can only remove the key when it is disabled. \u00a0This feature is good if you have curious children or have your laser in a shared area and want to limit use. \u00a0Just take the key out and hide it!<\/li>\n
- Remote Interlocks<\/strong> – This feature allows for addition of switches to your enclosure so when it is open, the laser will automatically turn off. \u00a0Also provides for the addition of an E Stop button for the laser<\/a>, which is always good for if you need to stop the laser super quick! \u00a0Add as many switches as you want to make a super safe area for your laser machine so nobody can accidentally look into the laser.<\/li>\n
- Power Fault Protection\u00a0<\/strong>– This one may seem like it is not needed, but hear us out. \u00a0Consider your power goes out in your area where the laser is located. \u00a0You were running your program and then everything is dark… \u00a0Power doesn’t come back on for awhile… long enough for you to forget that the laser was left ON! \u00a0You come back and are checking your laser and boom, the power is back on, right when you are looking straight at it. \u00a0Well, don’t worry because the laser will be disabled whenever the power to the driver is lost. \u00a0Press the reset button and you are back in action!<\/li>\n
- Emission Indicator\u00a0<\/strong>– \u00a0The small little LED on the front to let you know \u00a0your really super bright laser is on… \u00a0They require this in case you are using an infrared invisible laser.<\/li>\n<\/ul>\n

<\/h2>\nLaser Overview<\/h2>\n
This is the bigger 445nm 9mm laser diode with an added\u00a0our High Efficiency AR Coated Glass\u00a0lens.<\/a>\u00a0\u00a0 This laser\u00a0can run for extended times at 2.2W at 1.5amps! \u00a0This laser has a maximum limit of over 3W at 2.5amps and should only be over-driven like this for very short times. \u00a0 This level of power certainly creates the ability to cut more and do more with your laser. \u00a0 At the factory setting of 1.5amps @ 2.2W you should get about over 3000 hours of lifetime from the laser. \u00a0This laser also has internal ESD device for an extra level of static protection.<\/p>\n
This multi transverse mode laser diode component is pressed fit mounted in an aluminum housing and has an aluminum mountable heat-sink. \u00a0The laser is set in the heat sink with thermally conductive paste. \u00a0The front of the component contains a adjustable glass focusing lens for the laser output. \u00a0The laser has an ABSOLUTE MAXIMUM of over 3W at 2.5amps\u00a0and should only be run at this level for very short times. \u00a0Additional cooling techniques would be advisable if you want to run for extended periods at higher powers.<\/p>\n

<\/p>\nDriver Overview<\/h2>\n
This is the fourth generation of the popular High Current Laser Diode Driver series.\u00a0 We designed this new generation to follow the federal guidelines for safety compliance for high power Class 4 laser operation.\u00a0 This includes the use of a key enable switch, safety interlock system, power off reset, and laser LED indicators.\u00a0 All of these features make for a safer laser operation and will comply with federal laws regulating such operations.<\/p>\n
At the heart of the product are laser trimmed parallel regulators to give constant current without the large temperature dissipation of other regulators. 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.<\/p>\n
The high power laser diode driver is cost effective and easily integrated into industrial, research, or enthusiast projects and products.\u00a0 The driver can be operated in CW mode or in Input Control Mode to be interfaced to remote electronics.\u00a0 This design uses digital isolators for super fast response and input range while protecting the laser from deadly ground loops.\u00a0\u00a0 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.<\/p>\n
