The modular design of the disk laser offers you the utmost flexibility in every regard.Spinning disk confocal microscopy (SDCM) represents an alternative to LSCM.A thin disk laser is a type of diode-pumped solid-state (DPSS) laser technology in which the gain medium is comprised of a thin disk of typically Yb:YAG .Balises :LaserDiscMCA DiscoVisionDisk Drive: A disk drive is a technology that enables the reading, writing, deleting and modifying of data on a computer storage disk. Typically, it is a reference to any such media that predates the mainstream popularity of the DVD format. Another type of fiber laser is the fiber disk laser. In such lasers, the pump is not confined within the cladding of the fiber, but instead pump light is delivered across the core multiple times because it is coiled in on itself.
