Semiconductor diode-pumped solid-state laser with a small


Surface as the endoscopic approach. Resonator for the total reflection plane mirror at one end,ed hardy sverige, inside coated l064m high-reflective film to the other end of the output part of the reflection concave mirror radius of curvature of 100mm. Reflection wavelength of lO64Ftm rate of 90%. Nd: YAG crystal through the glossy coated l064Ml and 808nm AR coating. Before the experiment using He-Ne laser to adjust resonator cavity of about 80mm. 2 Experimental test test test include: a. Spectra. Monochromator on the use of Nd: YAG crystal output spontaneous emission spectrum, laser diode-pumped laser spectroscopy and laser output spectrum test; b. Output laser power test. Selective filters, attenuation filters, power meters and semiconductor photodiode detectors measure the output light intensity; c. Output laser mode test. L detector using needle beam scanning measurements can also be used to connect single-CCD detector and oscilloscope. Or under low-power image from the camera and software processing by the observations. The use of Benthem-TM300V monochromator. Not increase the output mirror, low-power pump in 0.5w used to test the Nd: YAG crystal the spontaneous radiation. Shown in Figure 4. You can see,franklin marshall outlet, and l064nm contains 946nm wavelength,ed hardy rea, 1064nm range and strong. Consistent with the characteristics of materials provided 92,094,abercrombie københavn,096 200 wavelength [m]} l000l020l040l0601080 indiscriminately 4Nd: YAG spontaneous emission test results in order to ensure stable output wavelength laser diode to increase the absorption efficiency of the pump light was tested, shown in Figure 5. You can see, the best option just pumped 808nm,franklin and marshall sale, the peak wavelength consistent with the basic installation and resonant optical cavity after adjustment. Tube in the laser diode to move near the threshold pump power of 1W,abercrombie paris, the output wavelength of the laser output only l064nfn, shown in Figure 6. Measured at different pump power output power changes, each laser diode drive current up to 0.75A. Corresponding to the total pump power of 6W, the maximum laser output power of about 2w. Slope efficiency of nearly 50%, light a light conversion efficiency of about 33%. In the laser optical output thrust Phi l Torr glutinous saliva / am Figure 6 laser output wavelength test added 1064n / n selectivity filter through the filter and attenuation,franklin and marshall, the use of photoelectric detectors, and RS-E2043 amplifier a light test can be pump power and output power obtained approximate linear relationship exists. Further model analysis showed that the output beam in the horizontal and vertical intensity distribution of the test are approximately Gaussian. Scan profile even close to TEMm fundamental mode mode. 4 summarizes the findings in this small laser diode-pumped Nd: YAG solid-state laser development situation. Describes the characteristics of the laser gain medium and selection, diode-pumped characteristics and considerations, design considerations of optical resonator and the experimental test results.
