Laser diode benches (LDBs) with lasing wavelength of 808 nm were developed, manufactured and endurance-tested for utilization as pump lasers for the Nd:YAG oscillator in the climate satellite MERLIN. The LDBs combine customized TE-polarized GaAs-base

In this letter we present new results on high power 970 nm ridge waveguide lasers based on an extreme double asymmetric epitaxial design. Due to an improved lateral-longitudinal design an M2-value below 1.1 and efficiency over 60% could be maintained

Highly efficient single-spatial mode lasers with wattlevel output power in the 9xx-nm wavelength range are of great interest for a variety of applications. We experimentally investigate the influence of the mesa widths on the electrooptical propertie

We report the first demonstration of 1.2 J-emission into long pulses ( $\ge 2$ ms) from passively cooled laser bars. These efficient high-fill-factor bars were developed for long-pulse pumping of Yb:CaF2-laser media at a power level of 600 W. The spa

High power 9xx-nm broad-area lasers with improved beam quality are required for many applications, but the physical limitations remain unclear, especially the relative importance of free-carrier and self-heating effects. Experimental data are, theref

Low-fill-factor laser bars composed of five narrow-stripe broad-area lasers (30 mu m x 6000 mu m) with monolithic spectral stabilization are presented. Each laser on the bar emits at a unique wavelength from 970 to 980 nm with a channel spacing of 2.

The use of long resonators (for improved thermal and electrical resistance) and advanced facet passivation (for high power) is shown to enable Joule-class pulse emission from single passively cooled 1-cm diode laser bars emitting at 940 nm. Bars on C

We demonstrate a continuous-wave 460-nm com- pact visible laser module having a footprint of 75 mm × 25 mm × 25 mm. This blue light source is achieved through single-pass second harmonic generation with a distributed Bragg reflec- tor tapered diode

In this work, we present the design and performance of a monolithic master oscillator tilted tapered power amplifier emitting at 1060 nm. The device consists of three sections: a 2 mm long ridge waveguide (RW) master oscillator (MO) section with two
