As with other Bookham New Focus tunable lasers, the TLM-8700
provides best -in-class low-noise performance with mode-hop-free tuning and
exceptional side-mode suppression. The aim of this passivation is to prevent Catastrophic Optical
Mirror Damage (COMD), which is otherwise a common problem in the
development of high brightness GaAs laser diodes.
