High-power distributed Bragg reflector lasers operating at 1065 nm

Abstract

A report is presented on distributed Bragg reflector lasers emitting in excess of 700 mW in a single-spatial and single-spectral mode at 1065 nm. The threshold current of these devices is $30 mA, there is an L-I slope of 0.74 W=A, and a sidemode suppression ratio greater than 30 dB. The current and thermal tuning are 0.016 Å =mA and 0.7 Å = C, respectively.

High-Power, High-Efficiency Monolithic Edge-Emitting GaAs-Based Lasers with Narrow Spectral Widths

“…High-power single-lateral-mode DFB and DBR lasers have been realized at 650nm (Pezeshki et al, 1998), between 760 and 800nm (Inoguchi et al, 1994;Morris et al, 1995;Takigawa et al, 1989;Wenzel et al, 2004a), between 850 and 900nm (Klehr et al, 2007b;Major et al, 1994;Price et al, 2006;Vermersch et al, 2008;Wenzel et al, 2002), between 940 and 990nm Fricke et al, 2005;Klehr et al, 2007a;Lammert et al, 1998;Mü ller et al, 2004;Nichols et al, 1993;Paschke et al, 2010;Sin and Horikawa, 1993;Wenzel et al, 2006a,b;Yang et al, 1998), and between 1060 and 1090nm (Achtenhagen et al, 2007;Hofmann et al, 1999Hofmann et al, , 2000aMajor and Welch, 1993;Nguyen et al, 2007). High-power single-lateral-mode DFB and DBR lasers have been realized at 650nm (Pezeshki et al, 1998), between 760 and 800nm (Inoguchi et al, 1994;Morris et al, 1995;Takigawa et al, 1989;Wenzel et al, 2004a), between 850 and 900nm (Klehr et al, 2007b;Major et al, 1994;Price et al, 2006;Vermersch et al, 2008;Wenzel et al, 2002), between 940 and 990nm Fricke et al, 2005;Klehr et al, 2007a;Lammert et al, 1998;Mü ller et al, 2004;…”

Blue‐green light generation using high brilliance edge emitting diode lasers

“…Although the phase in DBR lasers can be controlled, these devices tend to show mode hoping that results in nonlinearities in the light-current characteristics. High output powers of up to 700 mW from single emitter chips and high reliability close to 10,000 hours could be demonstrated [95,96]. A distributed feedback (DFB) diode laser is depicted in Fig.…”

Novel Band-Reject Filter Design Using Multilayer Bragg Mirror At 1550 Nm

“…Bragg reflectors have already attracted interest of researchers for their possible novel applications as optical transmitter [1][2], LED [3], reflectivity modulators [4], solar cell [5]. Highly transparent dielectric materials are required are used to construct Bragg mirrors in order to minimize the loss due to optical absorption [6][7][8].…”
