The optical absorption or emission data of Tm:YAG (Tm:Y3Al5O12). This data was part of the NASA Laser Spectra Database found on the web until December of 2005. This information was created by Pat Cross working at the NASA Langley Research Center. I have reworked the data to produce these interactive graphs and to provide direct links to text files containing the raw and manipulated data. Although I have tried to be careful, I may have introduced some errors; the cautious user is advised to compare these results with the original sources.

You can resize any of the graphs by clicking and dragging a rectangle. If you hover the mouse over the line on the graph, you will see a pop-up showing the coordinates. One of the icons in the upper right corner will let you export the graph in other formats.


The spectra was collected by TLL on 25 July 1988. The sample was 4.0000 mm thick. The sample orientation was unknown.

Spectra were recorded from 300 to 1950nm every 0.2nm at room temperature. The incident light had unknown polarization.
