COOLED MULTI-MODE LASERS(EM339)
High reliability fiber-coupled designs in 14-pin butterfly package
The Gooch & Housego high brightness laser (HPL) has high brightness with a fiber-coupled output power.
The HPL is ideal for use in a variety of applications where brightness is essential with a reliability and robust packaging.
The high power laser device is hermetically sealed into an industry standard 14-pin butterfly metal ceramic package. The butterfly package has a Peltier cooler for chip temperature control and thermistor for temperature monitoring. The higher power laser is pigtailed using a step index fiber with a 0.22 numerical aperture, 105 micron core fiber.
