报告摘要:

Owing to their fine spectral and angular filtering capability, a new type of optical components - volume Bragg gratings (VBG) - proved to be indispensable for numerous applications in optics and photonics. In the recent decade VBGs in photo-thermo-reflective (PTR) glass have found wide utilization in various applications, such as longitudinal and transverse mode selection in diode, fiber, and solid-state laser resonators, stretchers and compressors for picosecond and femtosecond lasers, mirrors for high brightness dense spectral beam combining, angular beam deflectors/magnifiers, and ultra-narrow line filters for Raman spectroscopy. In this presentation we will review recent progress in VBG technologies and demonstrate achievements in several areas of VBG applications such as ultra-low frequency (THz) Raman spectroscopy, high power narrow band diode lasers, ultra-short pulse lasers, and high power spectral beam combining. Also unique properties of VBGs enable recording of multiple elements in the same volume of recording material (volume multiplexing). In the presentation we will review a variety of novel optical components that can be created using this technology.
