摘要：

Properties of new pulsed-diode-pumped Er:YVO4 and Er:YVO4+CaO microchip lasers working in an "eye-safe" spectral region were investigated. As a pumping source, a fiber coupled (core diameter-200 mu m) laser diode emitting radiation at wavelength 976 nm was used. The laser diode was operating in pulsed regime with 3 ms pulse width, and 20 Hz repetition rate, The result obtained was 175 mW and 152 mW output peak power for the Er:YVO4 and Er:YVO4+CaO lasers, respectively The maximal efficiency with respect to the absorbed power was similar to 5%. The laser emission for Er:YVO4 microchip was observed in detail in the range 1593 nm to 1604 nm with respect to pumping, However, for Er:YVO4+CaO crystal only 1604 nm was generated.
