Diode-pumped passively mode-locked Yb³⁺-doped yttrium lanthanum oxide ceramic laser

Abstract

A diode-pumped picosecond laser was demonstrated with Yb 3+ -doped yttrium lanthanum oxide transparent laser ceramic Yb:(Y 1−x La x ) 2 O 3 (x = 0.1), which was fabricated with nanopowders and sintered in H 2 atmosphere. Passive modelocking was realized for the first time to our knowledge with a semiconductor saturable absorber mirror, generating pulses of 174 ps at the central wavelength 1032.5 nm with the average output power 162 mW under a diode-laser pump power of 3.2 W.

“…In addition, Yb 3+ doped media have broader absorp tion spectrum and broader emission bandwidths. The Yb 3+ doped oxy orthosilicates crystals have been real ized to exhibit excellent broadband performance, large ground state splitting and high thermal conduc tivity [3][4][5][6][7]. Efficient mode locked laser operations have already been demonstrated in numerous of Yb 3+ doped materials [8][9][10][11][12][13][14][15][16].…”

Fast mirrors for femtosecond passive mode-locked near-infrared lasers

“…Ultrashort pulse generation by laser longitudinal mode-locking was first realized in dye lasers with other dyes in a solution as a saturable absorber (see [1] and references therein). The general trend to replace pumping gas lasers (in particular, argon ion laser) and dyes as active media by more compact and reliable solid-state systems has led to the development of high power pumping semiconductor diodes, new efficient solid state laser crystals (in particular, Yb 3+ in different crystal matrices [2][3][4][5][6][7][8][9][10][11][12][13][14][15]), and a new class of saturable absorbers based on semiconductor quantum wells or quantum dots [16]-SESAMs.…”

“…In addition, compared with Nd 3 -doped media, Yb 3 -doped media have a broader absorption spectrum and broader emission bandwidths [4]. Yb 3 -doped oxyorthosilicate crystals have been shown to exhibit excellent broadband performance, large ground-state splitting, and high thermal conductivity [5][6][7]. Efficient mode-locked laser operations have already been demonstrated in numerous Yb 3 -doped materials [8][9][10][11][12][13].…”
