 Today we are introducing a brand new 532nm 5W solid-state laser. This laser now uses a touchscreen power supply. The power supply has a built-in cooling fan. This laser efficiently generates 532nm green light by frequency doubling the solid-state gain medium pumped by an infrared laser diode. Its core advantage lies in achieving high power output while maintaining excellent beam quality, low noise, and good stability—characteristics that make it outstanding in industrial and medical applications. Instructions for use: Turn on the power switch. The 'POWER' light will illuminate. After the machine starts, it will automatically jump to the current adjustment page. Here, we can adjust the current value to adjust the output power. Click the '+' and '-' buttons to the right of 'Current' to adjust the current. 1000 represents the full power current. The 'X 50' at the top represents an adjustment step of 50, and the 'X 1' in the second row repr...

 It is 532nm DPSS laser source . This laser source can be controlled by software. The connection of the laser and the PC software, using the RS232 communication protocol. The laser supports two modes of operation CW/Modulation, and an external signal input is required when switching to Modulation. Here is the free space output, and it is also possible to customize the fiber-coupled laser .  Software operation. Click the [Open COM] button to connect the control circuit on the laser.  Multiple laser operating parameters can be viewed/set in the software.  As a special reminder, it is necessary to set a maximum working current parameter according to the current laser first, so as to avoid the current of the later regulation being too high and damaging the laser. 

 It's a 543nm 10mW DPSS laser system . The back of the laser head is equipped with a cooling fan. There are 3 working modes available on the back of the laser power supply, CW, TTL and Analog. The red button is pressed to be ON, and the power is turned on. When the safety key is turned ON, laser output starts at this time. Rotate the'Adjustor' button and turn it clockwise to increase the current, thereby increasing the laser output power. Let's check it now. The center wavelength is 542.8nm. And its spot is perfectly round, it is TEM00 mode. 

It is 532nm high power dpss laser with adjustable power supply, the output power can be adjusted from 0 to 5000mW. This laser support CW and TTL/Analog modulation working mode. And the cooling method of the laser is TEC and cooling fan. 5W is a very high laser power, it is necessary to wear safety glasses during operation. Let's check it now. This 532nm laser is made of high quality high quality nonlinear crystal and collimating lens, with temperature control of high performance driving power, the active temperature control, with high efficiency, good stability, good beam quality, low noise, strong anti-jamming, good consistency, compact structure, miniaturization, long life and so on. This product are widely used in medicine, laser show, isotope separation, ultra-high density optical storage, precision materials processing, lithography, spectrum analysis etc... The following is the test data report and spectrum diagram of the 532nm 5W DPSS laser .

Structurally, the laser requires a resonant cavity, a pump source, and the amplifier only needs to be pumped without the need for oscillation. The laser is converted into laser light by the pump light , and then the laser is continuously oscillated and amplified, and the amplifier needs to inject the signal laser in the early stage, and its function is to amplify the signal laser. The laser is a light source that can directly emit light and output an optical signal. The laser switch is controlled by the input electrical signal, and the input electrical signal is modulated into an optical signal, and then the optical signal is output. Fiber amplifier , not a light source. It converts the externally input electrical energy into pump light. When the signal light is incident, under the stimulation of the incident light, the energy level of the pump light transitions, and the energy of the pump light is transferred to the signal light, and the signal light is transmitted. The pow...
