In some implementations, a laser diode array may comprise a cavity that includes a rear facet and a front facet and multiple emitters that are transversely single mode and disposed within the cavity. In some implementations, the multiple emitters each include a seeding section having a constant emitter width that is single mode at the rear facet and a flared section having a monotonically expanding emitter width that increases adiabatically over a majority of a length of the cavity such that outputs from the multiple emitters are single mode at the front facet. In some implementations, the emitter width is less than twenty micrometers at the front facet.
