Fast Switching Dual-Frequency Liquid Crystal Optical Retarder, Driven by an Amplitude and Frequency Modulated Voltage
We demonstrate theoretically and experimentally a fast-switching nematic optical retarder capable to switch a few microns of optical retardation in less than 1 ms. For example, a nematic cell of thickness 14.5 mm switches 0.3 mm of retardation within 0.15 ms and 2.5 mm within 0.5 ms for single passage of beam. The corresponding figure of merit is two orders of magnitude higher than the one know...
متن کاملTm:germanate Fiber Laser: Tuning And Q-switching
A Tm:germanate fiber laser produced >0.25 mJ/pulse in a 45 ns pulse. It is capable of producing multiple Q-switched pulses from a single pump pulse. With the addition of a diffraction grating, Tm:germanate fiber lasers produced a wide, but length dependent, tuning range. By selecting the fiber length, the tuning range extends from 1.88 to 2.04 μm. These traits make Tm:germanate lasers suitable ...
متن کاملMode-locking and Q-switching in multi-wavelength fiber ring laser using low frequency phase modulation.
We describe experimental investigation of pulsed output from a multi-wavelength fiber ring laser incorporating low frequency phase modulation with large modulation amplitude. The Erbium-doped fiber (EDF) ring laser generated more than 8 wavelength channels with the help of a phase modulator operating at 26.2 kHz and a periodic intra-cavity filter. For most cases, the laser output is pulsed in t...
متن کاملSCPEM-Q-switching of a fiber-rod-laser.
We demonstrate high-frequency Q-switching of a fiber rod laser with a Single-Crystal Photo-Elastic Modulator (SCPEM) made of a LiTaO₃₋ crystal. This type of photo-elastic modulator can be driven simultaneously with two different eigenmodes to achieve a shorter rise time, which is essential for high-power operation. When operated in the laser cavity, a pulse repetition frequency of 183.6 kHz wit...
متن کامل55.2: Fast Switching Dual-Frequency Liquid Crystal Optical Retarder, Driven by an Amplitude and Frequency Modulated Voltage
We employed amplitude and frequency modulated voltage in fast switching optical retarder with a high pretilt angle dual-frequency nematic cell. We obtained the response times 150 – 500 μs for an optical retardation shift on 0.3 – 2.2 μm in optical retarder with 12 μm thick nematic cell. The results could be used in beam steering, adaptive optics and display devices.
