What is the polarization ratio of the listed lasers?
A15: Laser diodes typically produce polarized beam. Typical polarization ratio for multi-mode laser diode based lasers is 30-50:1. In single mode lasers this ratio can be up to 100:1. For most of our DPSS lasers the ratios are 100:1. Not all lasers come with polarization axis indicator. Only some lasers have polarization axis indicator. In these lasers, customer may select the orientation of polarization axis in their purchase order. Q16. Do you still offer some of the older model lasers that were offered in the past? A16: Yes, most of our older model lasers are still available upon request. Q17. What type of line projectors do you offer? A17: We offer a wide variety of green or red line projector lasers for numerous applications from medical to industrial. Other than laser color and output power there are mainly three parameters determine the characteristic of a line projector. Projection length, line length and thickness. Q18. What determines the brightness (visibility) of a laser so
