Optical Isolators for Fiber Laser
Shinkosha's line of high-power in-line optical isolators for fiber lasers, spanning the 1 um, 1178 nm, telecom and 2 um bands, plus a backward-protection option.
High-power 1 um-band fiber isolator covering 1054-1074 nm at up to 5 W input power.
High-power 2 um-band fiber isolator covering 1930-2060 nm at up to 10 W input power.
High-power 2 um-band fiber isolator covering 1930-2060 nm at up to 30 W input power.
Isolator option that handles backward-travelling light away from the input fiber, cutting the temperature rise caused by back-reflection.
Dual-stage in-line fiber isolator for the 1064-1100 nm band, rated to 1 W input power.
Dual-stage telecom-band fiber isolator covering 1310-1620 nm at 0.3 to 3 W input power.
Dual-stage 2 um-band fiber isolator covering 1930-2060 nm at 0.3 W input power.
Single-stage in-line fiber isolator for the 1064-1100 nm band, rated to 2 W input power.
Single-stage in-line fiber isolator for the 1064-1100 nm band, rated to 3 W input power.
Single-stage in-line fiber isolator centred on 1178 nm, rated to 3 W input power.
