CAD and photo of ECDL-MOPA. (a) CAD Model of an ECDL-MOPA Module with Dimensions \(30 \times 80 \times 10~\mbox{mm}^{3}\). VHBG: volume holographic Bragg grating; μ-isolator: micro-optical isolator; μ-mirror: micro-mirror. The optical fibers exiting the fiber coupler are not shown in the figure. (b) ECDL-MOPA Laser Module for Operation at 1064 nm. The photograph shows the AlN ceramic body and the housing, as well as the optical and electrical feedthroughs. This figure is adapted from [136]
