MOD 1: QUESTIONS AND RESPONSES:

Q1: The specs indicate 527nm is desired, but would 532nm be acceptable?

R1: As we are seeking a replacement for an existing laser at 527 nm, we provided this specification in order to minimize the possibility of needing to change additional sections of the lidar system. (Note that this laser is the first step in producing the lidar transmitter light. The 527 nm output of this laser is frequency doubled to 263 nm in a CLBO crystal and that output is used to pump a Ce:LiCAF laser. Since each of these steps is wavelength dependent, we want to avoid having to change them to accommodate a 532 nm input.)

Q2: Regarding the cooling, it seems that you are currently using a water-cooled laser, correct? Is air-cooled acceptable? Or can a water-cooled solution be provided?

R2: An air-cooled laser would be desirable as long as it does not cause the laser head to be much larger than the size specifications provided. (The space available on the lidar structure is described in the specifications with the length and width dimensions being the most restrictive, while there could be some flexibility in the height if necessary.)
