Frequency stabilized three mode HeNe laser using nonlinear optical phenomena.
Accurate and traceable length metrology is employed by laser frequency stabilization. This paper describes a laser frequency stabilization technique as a secondary standard with a fractional frequency stability of 5.2x10(-10) with 2 mW of power, suitable for practical applications. The feedback stabilization is driven by an intrinsic mixed mode signal, caused by nonlinear optical phenomena with...
متن کاملSingle fundamental mode photonic crystal vertical cavity laser with improved output power - Electronics Letters
Introduction: The operation of a laser in a stable single fundamental mode is important for a variety of applications, such as short and midrange optical networks (high quality local area networks and storage area networks). For these purposes, vertical cavity surface-emitting lasers (VCSELs) show more promise in many cases over distributed feedback (DFB) lasers for a variety of reasons: easy a...
متن کاملPulsed, single-frequency, ring laser with a holographic output coupler.
A unidirectional, passively Q-switched, 2.05-μm Ho:YLF ring laser providing single-frequency, sub-mJ-energy, 100-200-ns-long laser pulses at a kHz rate is reported. The wavelength selection and "coarse" spectral narrowing is performed by utilizing a volume Bragg grating as a resonant, narrowband output coupler operated at a small angle away from normal incidence. Pulsed operation of the Ho:YLF ...
متن کاملComposite Cavity Fiber Laser with Asymmetric Output Intensity and Wavelength
The composite cavity fiber laser (CCFL) is relatively simple in its fabrication, as it is essentially three wavelength matched Bragg gratings in a section of doped fiber. By using internal feedback with unequal sub-cavity lengths, unidirectional CCFLs with significantly asymmetric output power from its two outputs can be achieved. Preliminary results also show that it is possible for the lasing...
متن کاملGinzburg-Landau model for mode competition and single-mode operation of a free-electron laser
Mode competition of a free-electron laser is modeled by the Ginzburg-Landau equation. The stability of a single-mode solution is analyzed, and connections are established with known instabilities of the GinzburgLandau equation. It is found that the principal mode with the largest gain is always stable and hence there is no Benjamin-Feir instability. However, the Eckhaus ~or phase! instability g...
