This is 520nm green laser module, the output power is 100mW. It has two working mode: CW and TTL modulation. Working in modulation mode, it supports 0~30kHz / 0-5V signal input. Let’s check it now.
It’s a 589nm yellow laser pen, and the laser power is 5mW. It use a CR2 3V battery. Install the battery with the positive terminal toward the tail. This pen is very portable.
It’s a 450nm high power blue laser system, the max output power is 50000mW. Heat sink can be added to laser head. And the output power can be adjusted by adjusting the current. This laser has three working mode: CW/TTL/Analog modulation.
High-power lasers usually generate large amounts of heat, which can easily damage the laser tube for a long time. It is not recommended to use high-power lasers for a long time. Figure 1. Withou the seat sink, can not work continuously for a long time Sometimes, the user needs to make the high-power laser work ...
The electromagnetic field distribution on the fiber end face is a zero-order Bessel function, and the Gaussian distribution is generally approximated as: Where r0 is the mode field radius of a single-mode fiber; r is the radial distance from any point on the fiber end face to the center. When the light wave transmitted through ...
It’s a Infrared fiber coupled laser, wavelength is 1540nm. it’s a C-band DFB laser, and it coupled a Single mode fiber. Let’s check it now.
The difference is usually price, feature set, and size. An instrument typically has a front panel with knobs and button adjustments and some form of display to track how the laser diode is operating. These can all be automated with computer control via USB, RS-232, RS-485, or GPIB. An instrument is usually powered by AC, ...
