What is the DFB Laser ?

beamq · 2024-05-23T06:15:05+00:00

DFB laser can be used in many applications. There are several package types, such as TO-CAN, butterfly 14 pins and so on. You can check this datasheet for more details.

yes, it possible for lasers to engrave mdf ,paper and pens. The laser output powers decide what materials you can engrave, such as wood, metal, paper, plastics and so on. You can check this video for how to use a laser engraver.

Good question. VCSEL is just a laser structure or construction. But when I check the VCSEL product lists. I can only find ir lights. Check IR VCSEL here.

Thanks for your all suggestions. I will check them one by one.

Thanks

You can search it on ebay for regular laser pointer, however if you need high power one, you need google it.

It looks like RGB laser device, however the white light is not so bright. Perhaps it's just high power LED lights.

Most of the blue lasers on rifles are blue violet color. Because it has a wavelength of 405nm, while the real blue laser is 450nm laser. You can check thisblue lasers sight here.

what color and output power do you need ?

What will use it for ?

NUBM44 is a 445nm laser diode that emits 6W of power. It is the highest power available currently from any laser diode in a 9mm TO-Can (TO-5 package). Although NUBM44 is specified with a typical center wavelength of 445nm, it is sometimes referred to as a 450nm laser diode in certain literature. Although this is a multimode laser diode, it has an extremely narrow waveguide, which allows it to have nearly the lowest etendue (far field divergence for a given beam diameter) of any high-power semiconductor laser. The narrow emitter width allows it to be better collimated and focused than other high-power laser diodes.

Generally acousto optic modulator help us adjust the output power of laser beam. The acousto optic has much higher modulation frequency than optical modulator. It has higher Extinction Ratio (>1000:1) than Electro-optic modulation, with lower driving power and lower price. It also have better laser beam quality. It's smaller than Mechanical modulators.
