From the help file on Source Diode: The help entry has information relating these parameters to FWHM beam divergence.. It appears to me that what you wish to model is a pair of laser diodes on one die.. The separation of the two diodes appears to be 225 um center-to-center..Method For Laser Source Definition in ZEMAX™ | IL PhotonicsAmong those laser sources are multi-mode fiber lasers, multi-mode fiber-coupled diode lasers, excimers, multi-mode solid-state lasers, and VCSEL arrays.. While they have some disadvantages in terms of focus-ability, higher M 2 lasers offer higher power than single mode lasers and require lower precision of optical elements in the system..



Reduction of beam divergence angle in laser-diode .. - ScienceDirect

In the ZEMAX simulation, a 60 W laser-diode bar (typical values are shown in Table 2) has 19 emitters with a width of 150 μ m and a pitch of 500 μ m..The emitter positions of the laser-diode bar with a 2 μ m smile (parabola- and S-shaped) are shown in Fig.. 4..Reduction of the divergence angle depends on the decrease of the linear displacement..
