This book is intended as a textbook on laser physics for advanced undergraduates and first-year graduate students in physics and engineering who need to use lasers in their labs and want to understand the physical processes involved with the laser techniques in their fields of study. This book aims to provide a coherent theoretical framework on the light-matter interaction involved with lasers in such a way that students can easily understand the essential topics related to lasers and their applications and get accustomed to the latest cutting-edge research developments. Most of all, the content of this book is concise to be covered in a semester.

Representing some of the most exciting work in critical ethnic studies, the essays in this collection examine the production of racialized, gendered, and sexualized difference, and the possibilities for progressive coalitions, or the "strange affinities," afforded by nuanced comparative analyses of racial formations. The nationalist and identity-based concepts of race underlying the mid-twentieth-century movements for decolonization and social change are not adequate to the tasks of critiquing the racial configurations generated by neocolonialism and contesting its inequities. Contemporary regimes of power produce racialized, gendered, and sexualized violence and labor exploitation, and they render subjects redundant and disposable by creating new, nominally nonracialized categories of privilege and stigma. The editors of "Strange Affinities" contend that the greatest potential for developing much-needed alternative comparative methods lies in women of color feminism, and the related intellectual tradition that Roderick A. Ferguson has called queer of color critique. Exemplified by the work of Audre Lorde, Cherrie Moraga, Barbara Smith, and the Combahee River Collective, these critiques do not presume homogeneity across racial or national groups. Instead, they offer powerful relational analyses of the racialized, gendered, and sexualized valuation and devaluation of human life.

Universality is a dangerous concept, according to Grace Kyungwon Hong, one that has contributed to the rise of the U.S. nation-state that privileges the propertied individual. However, African American, Asian American, and Chicano people experience the same stretch of city sidewalk with varying degrees of safety, visibility, and surveillance. The Ruptures of American Capital examines two key social formations--women of color feminism and racialized immigrant women's culture--in order to argue that race and gender are contradictions within the history of U.S. capital that should be understood not as monolithic but as marked by its crises. Hong shows how women of color feminism identified ways in which nationalist forms of capital, such as the right to own property, were repressive. The Ruptures of American Capital demonstrates that racialized immigrant women's culture has brought to light contested modes of incorporation into consumer culture. Interweaving discussion of U.S. political economy with literary analyses (including readings from Booker T. Washington to Jessica Hagedorn) Hong challenges the individualism of the United States and the fetishization of difference that is one of the markers of globalization. Grace Kyungwon Hong is assistant professor of English and Asian American studies at the University of Wisconsin, Madison.
