532nm 7W High Power Diode Pumped Laser

This time it is a 532nm green DPSS laser commonly used in laboratories. Its output power can reach 7000mW.  A heat dissipation module is added to the bottom of the laser. There are 2 cooling fans at the bottom of the laser heat dissipation. There are two working modes, CW/Modulation, to choose from on the back of the power supply.


There is a protective cover on the interface where the laser head is connected to the laser power supply. When connecting, the protective cover needs to be removed first. The light outlet of the laser head has a protective cover, which must be removed before starting the machine.

The Knob on the front of the power supply is used to adjust the current, thereby controlling the laser output power. Adjust the output power to maximum. After preheating for about 1 minute, the laser can output continuously and stably.

The high power green laser beam. The following are the effects of indoor shooting during the day.



TEM00 Lab Laser 532nm 15mW SM Fiber Laser Source

The demonstration in our laboratory this time is a 532nm 15mw single-mode fiber laser. It has an LCD display to show the current power of the laser. The output power of this laser can be adjusted from 10% to 100%, and the adjustment accuracy is 0.1mW. Let’s check it now.

The back of the laser has an RS232 interface. It can be customized for software control functions. The key controls the ON/OFF of the laser. Here is SM fiber, and PM fiber can also be customized.

589nm 3W Yellow DPSS Laser For Scientific Research

The 589nm yellow laser is a new light source that has important applications in spectroscopy, laser positioning and navigation, astronomy, and other fields. It also has broad application prospects in the fields of laser sodium guide, laser radar, laser medical, stage performance, urban viewing, defense military and scientific research.

In the video above is a 589nm 3W yellow DPSS laser system. It has two working modes, CW and Modulation, and the switch button is on the back of the laser power supply. Trigger is the modulation signal input interface. There is a protective cover on the connector of the laser module and the laser power supply cable, and the protective cover must be removed before connecting.





772nm Fiber Laser CW Working Mode Operation Video

What we are going to demonstrate in today’s video is a 772nm 1W fiber coupled laser. The output power of the laser is adjustable from 0 to 1000mW, which can be adjusted by the knob. It supports 3 working modes, CW/TTL/Analog, switch the working mode on the back of the laser power supply. In TTL/Analog modulation mode, an external modulation signal needs to be connected.

The optical fiber is pluggable and customizable. The fiber core diameter,fiber length and interface can be customized according to customer needs. 100μm to 1000μm fiber is optional, the coupling efficiency of different fibers will be somewhat different. The larger the core diameter, the higher the coupling efficiency, usually the coupling efficiency is 80%~90%.

The 772nm laser is a near-infrared laser, and the light spot is dim.
