Jechow A, Lichtner M, Menzel R, Radziunas M, Skoczowsky D, Vladimirov AG.
PMID: 19997179
Opt Express. 2009 Oct 26;17(22):19599-604. doi: 10.1364/OE.17.019599.

Stripe-array diode lasers naturally operate in an anti-phase supermode. This produces a sharp double lobe far field at angles +/-alpha depending on the period of the array. In this paper a 40 emitter gain guided stripe-array laterally coupled by...

Opt Express. 2012 Mar 26;20(7):7002-7. doi: 10.1364/OE.20.007002.

We report on the generation and amplification of pulses with pulse widths of 400 - 1000 ps at 1064 nm. For pulse generation an ultra-fast semiconductor modulator is used that modulates a cw-beam of a DFB diode laser. The...

Evaluation of Different Dental Lasers' Ability to Congeal Pooled Blood: An In Vitro Study.

The International journal of periodontics & restorative dentistry

Losin KJ, Yukna R, Powell C, Tippets J, Font K.
