UQTL100型 可调谐半导体激光放大器
(UQTL100 Tunable Amplified Diode Lasers）

产品介绍 （Products Introduction）

UQTL100型 可调谐半导体激光放大器是利用半导体材料的受激辐射放大原理，实现相干光放大的器件[1]。可调谐半导体激光放大器主要由半导体激光放大器芯片与驱动电源组成，半导体激光放大器芯片的有源区采用体双异质结结构，在几何上成锥型结构，它可以对入射激光进行行波放大，即将工作电流转化为载流子的反转粒子，使注入种子光幅度放大，而同时保持注入种子光的偏振，线宽和频率等基本物理特性。随着工作电流的增加，输出光功率也成一定函数关系增长。由于UQTL100型可调谐半导体激光放大器具有较宽的增益带宽，当注入光波长发生变化时，放大器的激光输出波长也随之变化，具有波长调谐功能。UQTL100型可调谐半导体激光放大器是优立光太公司与北京大学联合设计的一种新型结构的放大器[2]，具有体积小、调节方便、增益带宽宽、便于集成等优点。为了获得高质量的激光输出，推荐使用UQEL100可调谐半导体激光器作为主激光器。

Product Introduction	Principle of a tapered semiconductor amplifier

Product Introduction

UQT100 tunable semiconductor laser amplifier (TSLA) is a device for coherent amplification of light based on principle of stimulated emission amplification[1]. TSLA mainly consists of an amplifier chip and a electrical driver. The semiconductor amplifier chip is structured of heterodiode material in tapered configuration. It could boost the seed light power with single path by a factor of approximately 100 while retaining the favorable spectral properties of the master laser, such as polarization, lindwidth and laser frequency etc. The output power of TSLA is proportional to the injection current while input light intensity is fixed. TSLA can provid wide gain bandwidth, which possesses good tuning property. UQTL100 tunable semiconductor laser amplifier has been well designed by Peking University and UinQuanta Technology Co., Ltd, it takes the advantages in small size, easy adjustment, wide tunable range, integration available etc[2]. To obtain the high quality output of UQT100, the master laser UQEL100 is recommended.
