diode array pumped er yb phosphate glass laser
Applied Physics Letters, 1992Co-Authors: Andrew J Hutchinson, Toomas H. AllikAbstract:A diode‐array side‐pumped Er, Yb: phosphate glass laser has been constructed. Pumped with two 970 nm, InGaAs strained‐layer diode arrays, a long Pulse slope efficiency of 14% was obtained, with thresholds of 60 mJ input, a maximum Output Pulse energy of 20 mJ, and with Output wavelengths at 1545±12 nm. When Q‐switched, the laser generated 0.3 mJ, 50 ns FWHM Pulses at an Output wavelength of 1533±1 nm. Visible upconversion emission in the laser rod was observed.

broadly tunable high power operation of an all solid state titanium doped sapphire laser system
Optics Letters, 1991Co-Authors: T R Steele, D C Gerstenberger, A Drobshoff, R W WallaceAbstract:Broadly tunable and high-power operation of a titanium-doped sapphire laser is obtained with a diode-laser-pumped frequency-doubled Nd:YAG laser as the pump source. A maximum broadband (FWHM = 25 nm) Output Pulse energy of 720 μJ at 795 nm in a TEM00 mode is obtained for 1850 μJ of energy of 532-nm pump light. A minimum Pulse duration of 7 ns is obtained from a 40-mm-long cavity. With the use of an intracavity prism, the Ti:sapphire laser is tunable continuously over the 696–1000-nm spectral range (with three different mirror sets).

tea co2 laser simulator a software tool to predict the Output Pulse characteristics of tea co2 laser
Computer Physics Communications, 2005Co-Authors: Abdul B GhaniAbstract:Abstract “TEA CO 2 Laser Simulator” has been designed to simulate the dynamic emission processes of the TEA CO 2 laser based on the six-temperature model. The program predicts the behavior of the laser Output Pulse (power, energy, Pulse duration, delay time, FWHM, etc.) depending on the physical and geometrical input parameters (pressure ratio of gas mixture, reflecting area of the Output mirror, media length, losses, filling and decay factors, etc.). Program summary Title of program: TEA_CO2 Catalogue identifier: ADVW Program summary URL: http://cpc.cs.qub.ac.uk/summaries/ADVW Program obtainable from: CPC Program Library, Queen's University of Belfast, N. Ireland Computer: P.IV DELL PC Setup: Atomic Energy Commission of Syria, Scientific Services Department, Mathematics and Informatics Division Operating system: MS-Windows 9x, 2000, XP Programming language: Delphi 6.0 No. of lines in distributed program, including test data, etc.: 47 315 No. of bytes in distributed program, including test data, etc.: 7 681 109 Distribution format: tar.gz Classification: 15 Laser Physics Nature of the physical problem: “TEA CO 2 Laser Simulator” is a program that predicts the behavior of the laser Output Pulse by studying the effect of the physical and geometrical input parameters on the characteristics of the Output laser Pulse. The laser active medium consists of a CO 2 –N 2 –He gas mixture. Method of solution: Six-temperature model, for the dynamics emission of TEA CO 2 laser, has been adapted in order to predict the parameters of laser Output Pulses. A simulation of the laser electrical pumping was carried out using two approaches; empirical function equation (8) and differential equation (9). Typical running time: The program's running time mainly depends on both integration interval and step; for a 4 μs period of time and 0.001 μs integration step (defaults values used in the program), the running time will be about 4 seconds. Restrictions on the complexity: Using a very small integration step might leads to stop the program run due to the huge number of calculating points and to a small paging file size of the MS-Windows virtual memory. In such case, it is recommended to enlarge the paging file size to the appropriate size, or to use a bigger value of integration step.
