So a wile back I did a group buy for these diodes and when I posted the pics people were disappointed because they thought they were single mode.

well at selem I Compared one of these diodes to a Pl450 single mode diode and was stunned to find that these diodes had ever so slight better specs.
From left to right are as follows Pl450, 594nm HeNe, and NDB7242E
Dr Sam who was at the event said these diodes are most likely single mode despite what the spec sheet says.
I am ashamed to say I did not take distance measurements .
