We　report　a　diode　pumped　self-frequency-doubled　nonlinear　crystalline　waveguide　on　glass　fiber.　A　ribbon　fiber　has　been　drawn　on　the　glass　composition　of　50GeO(2)-25B(2)O(3)-25(La,　Yb)(2)O-3.　Surface　channel　waveguides　have　been　written　on　the　surface　of　the　ribbon　fiber,　using　space-selective　laser　heating　method　with　the　assistance　of　a　244　nm　CW　UV　laser.　The　Raman　spectrum　of　the　written　area　indicates　that　the　waveguide　is　composed　of　structure-deformed　nonlinear　(La,　Yb)　BGeO5　crystal.　The　laser-induced　surface　wavy　cracks　have　also　been　observed　and　the　forming　mechanism　of　the　wavy　cracks　has　been　discussed.　Efficient　second　harmonic　generation　has　been　observed　from　the　laser-induced　crystalline　waveguide,　using　a　976　nm　diode　pump.　13　mu　W　of　488　nm　output　has　been　observed　from　a　17mm　long　waveguide　with　26.0mW　of　launched　diode　pump　power,　corresponding　to　a　normalized　conversion　efficiency　of　4.4%　W-1.
