A diode pumped ytterbium-doped lutetium aluminum garnet (Yb:LuAG) ceramic laser is reported for the first time to our knowledge. Using the solid state reactive vacuum sintering technique we have successfully fabricated high optical quality Yb:LuAG ceramics. We show that even with an uncoated Yb:LuAG ceramic sample a maximum output power of 7 W could be achieved under 13 W absorbed pump power, a...
A time-of-flight mass spectrometer (TOF-MS) developed in our laboratory at Isfahan University of Technology is described here. The TOF-MS instrument uses laser as the ionization source which provides an opportunity to investigate the ions formed in laser ablation or desorption. The TOF-MS has an ionization chamber containing an accelerator and an ion lens to focus the ions into a one meter line...
Microfluidic dye lasers (MDL) have recently emerged as promising candidates to facilitate the fusion of optics and fluidics at the microscale. Their primary advantage over gas or solid state lasers is the inherent wavelength tunabililty which can be achieved by changing the type of dye used, the dye concentration, or the host solution. Here, we report on the design and characterization of a MDL...
In recent years, great attention has been paid to high peak power all-solid-state pulsed blue-green lasers [1–4] for some applications such as spectroscopy, display, optical data storage, coherent telecommunications, remote sensing, medicine, etc. Such lasers are generally realized by intracavity or external cavity frequency doubling of cw laser-diode (LD)-pumped solid-state Q-switched Nd-doped...
A novel single frequency fiber laser with more than 100 mW output is presented. Low noise and a coherence length of >75 km make this laser extremely useful in sensing, LIDAR, and coherent communication applications. @2003 Optical Society of America OCIS codes: (060.2320) Fiber optics amplifiers and oscillators; (140.3570) Lao;ers. single-mode; (140.5680) Rare earth and transition metal solid-st...
Er:YGG is a promising candidate for greenhouse-gas LIDAR due to fortuitous transitions around key absorption lines of carbon-dioxide and methane. We present growth of crystal films by pulsed-laser-deposition, their spectroscopy and initial characterization as amplifiers. OCIS codes: (310.0310) Thin films; (220.4610) Optical fabrication; (230.7390) Waveguides, planar; (130.0130) Laser materials;...
A high energy double-pulsed Ho:Tm:YLF 2-μm laser amplifier has been demonstrated. 600 mJ per pulse pair under Qswitch operation is achieved with the gain of 4.4. This solid-state laser source can be used as lidar transmitter for multiple lidar applications such as coherent wind and carbon dioxide measurements.
This paper discusses methods for characterization of high power lasers. Specifically, these methods have been developed for the High Energy Laser Joint Technology Office and used for independent, government-sponsored testing in the 25 and 100 kW phases of the Joint High Power Solid State Laser program. Primarily this paper addresses measurement of power and beam quality.
