2.5 Laser Diode

There are two footprints to connect the laser diode: SMD (D1) and TO-CAN (J3). Use either of the two footprints to connect the laser. Resistor R21 (1Ω by default) is connected in series with the laser. This resistor acts as snubber, and therefore dampens the transient behavior of the laser current. R21 can be tweaked to change the output overshoot and ringing.
