Setting up LIGHWAVE 126 series laser

Our previous laser was removed in the past month. The laser LIGHTWAVE 126-1064-100 has been setup for our experiment. It is being powered by the LIGHWAVE 126-OPN-PS. See laserPS and laserhead to view connections. Turning the key, turns on both the laser power supply and laser head. Its recommended to use STANDBY button to turn the laser off, instead of using the key. Also, turning off the Power supply will reset everything to default configurations set by the company.

As this laser is too old, the manual is difficult to find online.

Acoording to the manual we have maximum emission level of 2W and can atleast provide a specified power of 100mW. This doesn't mean we can't have power below 100mW. We can lower the current to have lower power. The laser starts emitting at around 0.58A.

The plot for current vs. Power shows a linear increase in power with increase in current.

 I used a lens of F=50 mm infront of the power meter as the beam size was increasing with increase in power and it would have damaged the cascading of the power meter.

The power meter used here has max allowed incident laser of 2W.
