چکیده

We report direct and absolute temperature measurements in a diode-end-pumped Yb:YAG crystal, using a calibrated infrared camera, with a 60-μm spatial resolution. The heat transfer coefficient has been measured, for the first time to our knowledge, with four different types of thermal contact (H = 0.25, 0.28, 0.9 and 2.0 for bare contact, graphite layer, indium foil and heat sink grease respectively). The dynamics of thermal effects is also presented. PACS 42.55.Xi (Diode-pumped Lasers)

Demonstration of a compact 100 Hz, 0.1 J, diode-pumped picosecond laser.

We have demonstrated an all-diode-pumped Yb:YAG chirped pulse amplification laser that produces 100 mJ pulses of 5 ps duration at 100 Hz repetition rate. The compact laser system combines a room-temperature Yb:YAG regenerative amplifier for increased bandwidth and a cryogenically cooled Yb:YAG four-pass amplifier for improved heat dissipation and increased efficiency. The optical efficiency of ...

Diode-Pumped Tunable Yb:YAG Miniature Lasers At Room Temperature: Modeling And Experiment - Selected Topics in Quantum Electronics, IEEE Journal on

We present a simple design rule for diode-laserpumped quasi-three-level lasers by using the M2 factor. The validity of this model was demonstrated by diode-pumped Yb:YAG laser experiments. The maximum output power of 1.33 W and optical slope efficiency of 63% were obtained in a 400m Yb:YAGchip miniature laser. Using a 200m Yb:YAG chip, a 70% optical slope efficiency was reached. In a coupled-ca...

Highly efficient room-temperature Yb:YAG ceramic laser and regenerative amplifier.

A room-temperature, diode-pumped, pulsed Yb:YAG ceramic free-running laser with a 78% slope efficiency has been demonstrated. It has been shown that fine tuning of the mode diameter to the diameter of the pumped volume with a ratio of the pump to the mode diameter of 0.6 is important for achieving maximum laser efficiency with a Gaussian-like beam profile. A regenerative Yb:YAG ceramic amplifie...

Diode-Pumped Solid State Lasers

III The use ofdiode lasers instead ofHashlamps as optical pump sources for solid state lasers offers significant advantages such as higher efficiency and longer lifetime. We have demonstrated three novel lasers based on this technology. The first is a zig-zag slab laser pumped by hybrid planar microchannel-cooled diode arrays that allow high-repetition-rate operation in a pulsed mode. The secon...
