 Rue François Mitterrand Institut d'Optique d'Aquitaine 33400 Talence France |  SHIPS TODAY: AeroDIODE offers fiber-coupled laser diodes with very high brightness (meaning high power and high precision/small spot size when focusing) dedicated to micromachining or fiber laser pumping applications between 808 nm and 1550 nm as stock items or associated with a high power laser diode driver with air cooling. Most turn-key diode & driver solutions are optimized for single-shot to CW performances. Many multimode versions are available with CW emission up to 450 W in a 200-µm core multimode fiber or up to 250 W in a 135-µm core fiber or 160 W in a 105-µm core fiber. The highest brightness/power models are based on special laser diodes for 808 nm, 915 nm, 940 nm, 976 nm, 980 nm or 1064 nm. See also our tutorial on fiber-coupled laser diodes. |
