How do you compare laser diodes output beam profile with HeNe lasers output beam profile?
A3: Due to their internal chip structure typically laser diodes emit an oval shape beam profile. HeNe laser in general emits a more circular beam profile. With use of special beam corrective optics, LD output beam profile could be more circularized. Q4. What is the laser diode’s output beam divergence and how is it minimized? A4: Depends mostly on laser diode mode structure and its emitter size, beam divergence may be as high as 10mrad in each axis. Use of collimating optics and perhaps beam expanders enable reduction of beam divergence to below 1mrad. Q5. What is CDRH and what roll does it have in the laser industry? A5: CDRH stands for Center for Devices and Radiological Health and is a division of FDA that regulates all radiation emitting products in the USA. Q6. Is that possible to include additional built-in features with any of your lasers? A6: Yes, although most of lasers are listed with some standard features. More features can be added per customer request. In fact our experti
