Transfer of diode pumped Er:YLF laser radiation by hollow glass waveguides
Abstract A compact diode pumped Er:YLF laser emitting at wavelength 2825 nm was designed and constructed. Radiation delivery from this source by special hollow glass waveguides with inner diameters of 250, 320, 540, or 700 $$\upmu$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>μ</mml:mi> </mml:math> m was investigated. The power transmission was up to 91% for around 1 m long waveguide. Measured hollow glass waveguide with this efficient transfer could serve as an appropriate solution of diode pumped mid infrared laser radiation delivery.
