We report on the stable operation of a 2500-ppm thulium-doped ZBLAN upconversion fiber laser at 481 nm and the related problem of photodegradation associated with the formation of color centers. The output coupling is observed to affect the level of

We have investigated the dynamics of color center formation (darkening) in a 1000 ppm thulium-doped ZBLAN (ZrF 4 -BaF 2 .-LaF 3 -AlF 3 -NaF) optical fiber by ultraviolet (285, 300, 351, 364 nm) and infrared (1112 nm) exposures. We observe that color

Since most techniques of refractive surgery currently in use or being developed have the potential for significant side effects, there is a need for investigating alternative procedures. We herein report on the use of a pulsed CO2 laser beam delivere

We report on the observation of photoinduced absorption in four different thulium-doped ZBLAN fibers exposed to 1.12-μm light. The darkening rate is shown to follow a fourth-power dependence on the pumping intensity and a strong dependence on the Tm

The insertion of a saturable absorber in a laser resonator sustaining a fundamental mode of gaussian shape is shown to create an apodizing element with a nearly gaussian transmittance. A simple analysis predicts that such an element has little effect

The main features of a thulium-doped ZBLAN fiber laser are presented and compared to the results of a numerical analysis. Particularly, the problem of the photoinduced absorption arising from the formation of color-centers is addressed with special a

We present here the work performed by INO and the Canadian Coast Guard in developing a laser range light using a single site to replace conventional range lights requiring two sites. A single laser source and a temporal coding are used to indicate th

The performance of a diode-pumped Cr:LiSAF laser and its intracavity frequency-doubled operation is reported. Close to 1 W of quasi-cw power at 870 nm was obtained in multimode operation. Power in excess of 20-mW cw of TEM(00) second-harmonic power a
