We demonstrated nonlinear mirror mode-locking of a diode-pumped Nd:GdVO4 laser by using a 10 mm long KTP crystal. The stable CW mode locking can be reached with the relative low threshold pump power as low as 2.3W. The highest output power of 2.65W at the 10 W pump powers are generated with the 121-MHz repetition rate of pulses. It confirms the excellent laser performance of the Nd:GdVO4 for hi...

Hemangiomas that arise in cervical esophagus are extremely rare, representing 3.3% of all benign esophageal tumors. Although endoscopic mucosal resection (EMR) and potassium titanyl phosphate/yttrium aluminum garnet (KTP/YAG) laser therapy have been used with success for small tumors, the safety and efficacy in the case of large tumors remains uncertain. We report the successful resection of ce...

In this paper, an optical angle sensor with a birefringent transducer for measuring angular displacement based on a heterodyne interferometry is proposed. The achievable repeatability and linearity provide sufficient evidence for the practical use. As a result, a resolution of 5.8 ˆ 10 ́6 with a dynamic range of 5 ̋ has been achieved by utilizing a KTP (potassium titanyl phosphate) plate immersed...

In this work we present the development of an accousto-optically Q-switched Nd:YAG/KTP based compact laser producing 35 W of average green power at 532 nm under operation at 20 kHz repetition rate with simultaneous side and end-pumping configuration. 19.4% optical to optical conversion efficiency has been obtained. The width of the green pulses at the maximum operating power was measured to be ...
